Hi
We've had the same problem, trying to search inside do files for various commands. - in XP only though
The best (fastest, and free) solution is to install Google Desktop.
Under Desktop preferences, add the appropriate network drives you want to be indexed (i.e. if all your code sit's on the "S" drive, it won't be found by the GDS)
Next, go into the 'install plugins' section of the preferences and download "Larry's any text file indexer'
When you've installed it, Notepad opens and gives you a config file to edit. Insert the following lines
# STATA 9 Do files
AddNewExtension "do"
AddNewExtension "ado"
Save the changes and then let google do the first index...
If you search for something like "collapse(sum)" you'll get a list of all the stata do files that contain that piece of code.
Happy searching!
Cheers
Dan

Subject: st: poisson regression different data sets-dummy variables v xi
hi
i know that i can use the following
Use data1 , clear
Poisson y x
Predict file1_m, ir
Use data 2, clear
Predict file2_m , ir
My question relates to the use of the command xi, in the regression the command is
xi:poisson var1 i.var2 i.var3 var4 etc.
but when i try to apply the results from file 1 to file 2 , i get an error message, for this to work prior to any analysis would i have to create dummy variables in b oth of the data sets . I plan on running a series of regressions using different combnation of the independent vars and am therfore trying to automated the procedure as much as possible.
I could of course run all of the regressions in file one and output the seperate predicted varaibles to the second file, but thought using the above would be more efficient
this analyses will be repeated on several different country data sets, therefore looking for an efficient method
I trust that this explanation is ok

Subject: RE: st: version 5.0 to version 9.2
True enough, but if you're cycling over a numlist 1/`r'
you might as well translate this directly to
inspect `2'
local r=`r(N_unique)' - 1
forval v = 1/`r' {
matrix C[`v',1]=c`v'
}
and then this is a smidgen cleaner:
inspect `2'
local r = r(N_unique) - 1
forval v = 1/`r' {
matrix C[`v',1] = c`v'
}
and this is a smidgen shorter still,
although perhaps more difficult to read:
inspect `2'
forval v = 1/`= r(N_unique) - 1' {
matrix C[`v',1] = c`v'
}
But the code is all followed by a -matrix list C-.
And those -c1-, -c2-, etc. are presumably scalars,
that must exist already. So I don't understand this
really, I am just translating code.

The reason you get an error is that -xi- creates
new variables, and these variables are used in
your estimation command, but they are not created
in you second file. So what you need to do is to
make the same variables in data2, like in the
example below.
*------------- begin example -------------
sysuse auto, clear
recode rep78 1/2=3
/* create two files */
gen select = uniform() < .5
tempfile data1 data2
preserve
keep if select == 0
save `data1'
restore
keep if select == 1
save `data2'
/* Estimation */
use `data1', clear
xi i.rep78 /*create dummies*/
reg mpg length _I*
/* Prediction */
use `data2', clear
xi i.rep78 /*create dummies*/
predict xb, xb
*-------------- end example --------------

Subject: st: Logistic regression, changing order of variables
Hello everyone.
I am using logistic regression in the analysis of a database coming from
a study in Zimbabwe. A sample command is 'xi:logistic hiv i.age3 sexc
age'
The variable age3 is the age in 3 strata (2-4yrs, 5-11yrs, 12-17yrs). As
I currently have the coding, 0=2-4yrs, 1=5-11yrs, and 2=12-17yrs. Thus
the strata 2-4yrs is the point of comparison. In this case, the two
older strata both showed a reduced risk of infection.
However, I prefer to report the data in the context of which strata has
increased risk of infection. Is there a command I can use (or add to the
existing command 'xi:logistic hiv i.age3 sexc age') that would allow me
to change the order of strata during logistic analysis. That is to say,
if I want to use the 12-17 yr strata as the point of
comparison...without having to create a new variable in which I change
the coding.
Thank you
Todd

See -man xi- pages under the heading "Summary of controlling the
omitted dummy" to alter which dummy variable is omitted and used as
reference.

It can be done with -xi-, see -help xi- under the section
"Summary of controlling the omitted dummy". So you would type:
char age3[omit] 2
xi:logistic hiv i.age3 sexc age
I like to create my own dummies. That way I have more control
over the reference category, any other contrast I may like, and
the variable names. So I would prefer to do:
gen age2_4 = age3 == 0 if age3 < .
gen age5_11 = age3 == 1 if age3 < .
logistic hiv age2_4 age5_11 sexc age
Hope this helps,

Of the various solutions suggested,

(downloaded from http://www.wingrep.com/)
As far as I can see, it is not possible to configure
the search type within Windows XP as it is with Vista.
The free versions of Ultra-Edit & WinEdt are a time-limited.
(unlike Grep, which merely suggests you register.)
-find- from a DOS prompt gives too much text
(including files without the text searched for)
So thanks in particular to Al Feiveson's son.

If you wanted to avoid WinGrep's suggestion to register you could go
the whole hog, and use the original grep by installing Cygwin and
searching your files from within a UNIX-like shell.
(If I remember at the start of the thread you mentioned that you
didn't want to install a different OS, this provides the functionality
of an alternative OS under M$-Windows).

Thank you for that validation. And I agree with your assessment of
"over-protected" and "over-visualized".
I'm not really a champion of DOS in particular. (And what we are
dealing with is really the command environment of Windows, which is
not exactly the same as DOS.) I also find DOS (or the Windows
command environment) to be a bit disappointing, after having worked
in some others for many years. What I do prefer is the general
concept of a command environment -- old-fashioned, but very powerful
if you know how to use it. Evidently, many others agree, as some of
the other responses have been about programs that provide various
alternative command environments under Windows.

Subject: st: Multinomial endogenous dummy
Dear All:
I have a multinomial dummy variable that has 7 categories - coded 0 to 6.
This dummy is an endogenous explanatory variable in a model like the
following:
Y = a0 + a1*MultinomialDummy + a2*ExogenousVariables + errorterms
My question is how I should account for this dummy using STATA? All I guess
is that I should use mlogit to run the first-stage regression. I have no
clue what to get from the mologit to plug in the second-stage. I don't think
it's just a simple predicted value.
Since I am interested in the impact of each of the category of the
MultinomialDummy on my Y, some suggestions were made that I run the
following model instead:
Y = a0 + a1*Dummy1 + a2Dummy1*S1 + ... + a12*Dummy6 + a13*Dummy6*S6 +
a15*ExogenousVariables + errorterms
where Dummy1 is (1,0) when one of the category of the MultinomialDummy
variable above occurs, and so on for Dummy2 to Dummy6.
What S1 to S6 that are interacted with the dummies are a big puzzle to me.
Does anyone know what they are and how to get them by STATA or mlogit?
I'd greatly appreciate any comments on the econometric method and STATA.
Thanks,
Hinh

In addition to the DOS -find- command there is -findstr- which I use
quite frequently on my Windows XP machine. Even for file types which the
Windows Search includes, I prefer the output of this command when used
on text files. The -findstr- command has many more options, including -
/s -, which searches through all sub-directories. There is also
provision for handling regular expressions and pattern matching but I
have never used these and cannot say how well they perform.

I run adoupdate, all update a few day ago and now when I run adoupdate,
update I get the following:

Subject: st: Large data sets
Hi,
I need to work with large datasets (>700M, <2g), but Stata 9.2 does not
allow me to set memory above 500M (my computer should allow for up to 2g
memory setting).
I checked on Stata�s FAQs website
(http://www.stata.com/support/faqs/win/winmemory.html) and found out about
the hotfix patch 894472 that helps overcome this problem. I tried to execute
the hotfix patch from this website but got this message "Setup cannot update
Windows XP files because the language installed on your system is different
from the update language".
I tried to find a version in spanish (my system is set in spanish) but have
not succeded..
Does anyone know about a spanish version of this patch?
Thank you in advance,
Carmen

I don't know about a Spanish language version of the patch, but even without the
patch you should be able to allocate about 900m to Stata under XP. How much
physical memory do you have? Do you have lots of other programs running at the
same time? You may want to reduce the number of programs that start up
automatically and launch Stata with nothing else running to see if you can get
to something close to 900m.
There's still a good chance that you will actually need more than 900m if you
really need to use a 700m+ dataset. But you may be able to make the dataset
smaller: Can you drop some variables? Could you compress some variables using
value labels or smaller storage types or even using abbreviations in text
strings? Can you drop some observations for some analyses? All of these
options are worth exploring. Otherwise, you could switch to an OS that can
allocate more memory than XP -- Mac, Linux, even Windows Vista can allocate
more.

Subject: st: error r(7) from outreg
Nirina wants outreg to work with ivreg2. Her codes does not work
because ivreg2 does not always return a number in its scalars. In
other words, e(cdchi2) is probably missing from her regression result.
The following codes will work.
sysuse auto,clear
ivreg2 mpg price (headroom=rep78)
outreg using ivjune22, br addstat(F-stat, e(F), sargan, e(sargan))
The following code will not work because some of the scalars are
missing from ivreg2 scalars.
outreg using ivjune22, br addstat(F-stat, e(F), cragg, e(cdchi2), craggp,
e(cdchi2p), craggF, e(cdf), sargan, e(sargan), sarganp, e(sarganp))
To see what is contained or missing from ivreg2 scalars, type these:
ssc install outreg2, replace
outreg2 using ivjune22, br e(all) seeout
Her new codes would look like this:
outreg2 using ivjune22, br addstat(F-stat, e(F), cragg, e(cdchi2), craggp,
e(cdchi2p), craggF, e(cdf), sargan, e(sargan), sarganp, e(sarganp))
seeout

Subject: Wishlist st: Re: Large data sets
This brings up a general problem that I wonder if stata can fix, or has
fixed. I routinely use large datasets--by large I mean 4-10 gb. I use a
unix system managed by a computer center. Sometimes my data becomes so
large that there is no machine large enough to invoke stata and hold all
the data in memory.
I should also say that my models routinely take weeks or even months to
run, so I am resigned to waiting a long time for results. Speed is not my
interest.
So, I was wondering whether stata can, or has, made it possible to tell
stata to use a disk as virtual memory. I know this will slow down run
times substantially, and my 4 week job could easily become a 6 month job.
But, at present, my 4 week job cannot be run without more resources, and
that means waiting a year to get more money to buy more memory. So, even
at 6 months, that would be more than twice as fast as now.
I know this is not the common desire--I chuckle when someone complains
that it took 57 seconds to run something rather than the 35 seconds they
had expected, and wonder whether stata is efficient enough. Yes,
efficiency there would help me, too. But what would help far more is the
ability to just opt out of holding all the data in memory when I need to
do so.
FYI--Yes, I've done all the data reduction one might suggest (e.g., using
frequency weights for patterns in the data, and so forth) and no, for my
problem sampling will not be helpful because the models I am estimating
need all the data to address issues of sparseness in some parts of the
data, and sampling will prevent that gain in information.
So, how 'bout it stata--have you made it possible for one to use a disk as
virtual memory with a few commands and, if not, will you please do so?
Respectfully yours,
Sam
