Just loaded my Version 11 of Stata, and am really pleased with the new
features. The addition of having the PDFs of the manuals is quite a
bonus! Every fall, I teach a course that introduces about 70 new people
(all budding medical researchers) to Stata, and it continues to be an
invaluable teaching tool, as well as a highly efficient method for data
analysis. Keep up the great work!

Just a short thank-you note for a putting together a fine product and an
amazing group of people. My co-author and I just had a paper published in
the Journal of Political Economy. The entire analysis was conducted in
Stata. Stata handled the task effortlessly. Over the course of the past
year I have received fantastic support—without technical

My thanks to everyone at Stata. We teach our undergraduates Stata in the

We’ve been using our [...] copy of Stata 9 for over a year now, and
have been able to accomplish some tremendous things with it. I’d like
to extend warm thanks for your generosity, as well as some praise for a
really excellent piece of software.
First of all, Stata deserves high marks for being easy to learn.
Programming is so easy that I practically never write repetitive commands
I’ve been very pleased with Stata’s graphing abilities, and we
use Stata-generated graphs extensively in our political coverage to explain
poll averages and other quantitative data in ways that our competitors
can’t. (For example, see here:
click on the graph images to enlarge.) Stata performs so well that I'm
delighted to credit it at the bottom of every graph that we create.
Stata’s data-handling abilities are outstanding; I use Stata to comb
through databases when I’m doing preliminary research before starting on
articles, and I’ve developed lots of article ideas from data that Stata
makes it easy to examine.
In short, excellent software-the best program of any sort that I’ve
ever used. I look forward to opening it up every day.
Your user support at Stata is really the best I’ve ever experienced
from statistics software companies. SAS and SPSS don’t come anywhere

I succeeded in running my first (simple) logistic analysis within 30 minutes

one who wants to evaluate fit, and is described in to-the-point manuals. As

Incidentally, one of the really neat features of Stata is the indexing of
the STB through the search command. It is a major reason for submitting to
the STB rather than to SUGI. One of the things that I like about Stata is
that it has the feel of a small company that still cares about its users.
This is greatly appreciated.
Off the top of my head here are some reasons why I use Stata almost
It has the best coverage for biostatistics/epidemiology as far as I can see.
It is easy to install, but if you have any problems whatsoever, be it with
installation or otherwise, they have a hotline (1-800-STATA-PC) which is
high quality. They are honest; if they do not know the answer immediately
they will admit to it and get back to you on it, rather than try to con you
out of the question.
The capabilities include all the standard things (data filtering,
statistical models, great graphics) and some non-standard, but useful things
like survival (cox, logrank,...), Mantel–Haenszel, logistic (probit,
tobit,...), etc. Plus, if what you want is not there, they have a
programming language built in.
Works on all sorts of platforms, including the big three: Unix, Windows, and

kind, reassuring, and willing to be available for any future questions or

great in responding to the questions!
School of Management and Business,

I am writing to you today to offer my highest praise for the help I recently
received from your consultant, May. I wrote to Stata technical support last
week regarding how to obtain and plot weighted Schoenfeld residuals using
Stata. A complication was that previous versions of Stata had taken
advantage of a collection of user-written ado-files. I confess that I use
Stata only infrequently, typically for modeling tasks using the xt
commands, so I felt very out of my element with the query that I posted to
your Technical Support group regarding plotting residuals from Cox
proportional hazards models.
May handled my question promptly and with great aplomb. I was pleased that
she did not dismiss my questions because I was using another user’s
user-written ado-files. To the contrary, she diagnosed the functionality of
those files and showed me a much more efficient mechanism to obtain their
functionality by using new features in Stata 8. Most impressively, she went
beyond answering the questions I’d posed. Anticipating the context under
which I was posing my questions, she provided terrific commentary not only
on the Stata syntax, but also on the purpose of the analysis and in her note
she walked through an example of the code she provided, not only explaining
the code itself but also how to interpret the results. I was ecstatic that
May provided such a thoughtful, detailed response because while the code
alone would have been very useful to me, the code coupled with the
interpretation of the example data May used was far more useful to me as I
can now apply the code with confidence to my own data. Clearly, May is very
gifted at identifying a user’s level of expertise (or lack thereof, as was
the case for me) with a particular problem area and adapting her response to
match the user’s level of sophistication in any given area.
I hope this note conveys both the gratitude I feel towards May for her
outstanding responses over the past week and the esteem in which I hold your
Technical Support group. This experience will definitely prompt me to
recommend Stata to my colleagues and will encourage me to use Stata for more
of my modeling tasks than I do at present.

I had been having trouble with upgrading ado-files ... after considerable
effort, I received, quite unexpectedly, a phone call from Kevin Crow at
Stata Tech Support who had decided that since we were not getting anywhere
after many repeated email attempts, he would contact me personally to help.
I must say I was tremendously impressed to get that phone call. I had been
cautious in using up Stata Tech Support time in that I had used both email
(extensively) and the Statalist first, but my experiences with other tech
support providers make me aware that it is very very impressive to get that
kind help and concern about resolving my problem. My thanks, and kudos,
both to Kevin, and to Stata for providing that kind of support. Sure makes
buying the upgrades a great value!

from you, An Introduction
to Survival Analysis Using Stata by Cleves, et al. My main use of
Stata will be survival analysis, especially parametric regression analysis,

in that regard before buying the program.
I was not expecting much from a “company” book but was very
impressed with its completeness, accuracy, and informative style. The
authors spend as much effort in explaining ‘why’ as in telling
‘how’. I read the whole book, and even recommended it to
clinicians in a review article I just happened to be writing while I was

Benchmark Environmental Corp.
Three years ago, I started teaching a one week seminar at U Michigan’s
ICPSR Summer Training Program. Nobody at ICPSR had been using Stata, and
StataCorp generously provided copies of the program and documentation.
Three years later, Stata is becoming the software of choice in the classes.
This year, StataCorp offered a very generous price (the grad pac price) to
participants. Several people in my class were feeling a bit pressured to
make a decision and I told them not to worry that the folks at Stata are
very reasonable. Indeed, when these people called, those answering the phone
went to great lengths to work out POs, payment, and all the details. And,
the support staff at ICPSR report that the help they receive if they have a
problem is absolutely first rate.

report that everyone who has taken my suggestion to try Stata has been very

I ran a crossed random effect binary model today on some data I got this

for the study variable that’s random.
It ran on the first try, in under 15 minutes.
Now obviously this involves having “good” data with pretty big
effects, but as anyone who ran these kinds of models even a few years ago
can attest, estimating a crossed random effect is no easy task, but

Stata is a great software package. This dataset in current form has almost

I stood amazed at the speed—even more so if, for example, I compare it
with Excel, which I am also using with this dataset.

This kind of responsiveness is what makes Stata a first-class operation.
I switched virtually all of our analysis work from mainframe SAS to Stata on
the PC (and a little bit on UNIX) a few years ago and have never regretted
that decision for a second. Most impressive is the fact that you guys find
fixes for every problem or question that we have, quickly and efficiently.
And little by little, as Stata develops, we are dropping the other programs
we use, too. I don’t know of any other software company that responds as
well to its users’ questions, suggestions, and comments.
