I'm a new Stata user. While I'm very impressed with the range of statisticalAs Nick Cox says, the short answer is no. However, I myself usually get around this by using the -parmest- package, downloadable from SSC. (Type -ssc desc parmest- or -net search parmest- to find out more.) -parmest- creates output data sets with one observation per estimated parameter, or one observation per estimated parameter per by-group, and data on parameter estimates, confidence limits, P-values and other parameter attributes specified by the user. Once the user has such a data set in the memory, s/he can type something like

models which can be fitted in Stata and its programmability, I'm less impressed with the formatting of the standard modelling output (although I must admit to only having used regress so far). Often there is a spurious accuracy with too many significant digits in the output and decimal points are not often alligned. So my question is:

is there a GLOBAL way of setting/resetting the number of significant digits and the number of digits after the decimal point?

(I could do this in Glim 25 years ago!)

format estimate min95 max95 %8.2f

format p %8.1e

list parm estimate min95 max95 p

and have a listing of the parameter estimates to 2 decimal places, and the P-values in scientific notation (as P-values should be). It is also possible for users to do other tricks, like confidence interval plots for immediate impact in a presentation, which is ideally done using Nick Cox's very useful -hplot- command (type -ssc describe hplot- or -net search hplot-).

A tutorial on the use of the -parmest- package, containing some fairly advanced examples, can be found in the website of the 2002 UK Stata User Meeting at

http://ideas.repec.org/s/boc/usug02.html

where it can be downloaded. However, users are warned that some of the examples presented will now cause -parmest- to report an error, because -parmest- now requires the user to specify at least one of the options -saving-, -norestore- and/or -fast-, in order to specify whether s/he wants the output data set to be stored in a disk file, written to the memory (overwriting pre-existing data), or both. For these examples to work as presented, the user should specify the -norestore- option.

I hope this helps.
