Stata Users Group Meeting in Bern, November 2016 : a conference to remember

Stata Users Group Meetings

Stata Users Group Meetings


Dear members of the Stata Community,

The Stata User Group Meeting we have been holding in Bern the 17th of November 2016 has been a tremendous experience. It was the first Swiss Stata User Group Meeting with 45 participants, 10 speakers, one tasty lunch, 2 well-deserved coffee breaks, as well as more than interesting discussions about Stata applications.

Thanks to the University of Bern as well as the editor StataCorp, whose organisations supported us all the way through with this project, we were able to receive the attendees and speakers in the marvelous venue of the Haus der Universität Bern.

A first Swiss Stata User Group Meeting it was, but it’s been definitely cosmopolite: academics, students, researchers and executives from our country but also from France, Germany, Luxemburg etc. We even had the pleasure to hear speakers from the University of Freiburg in Germany, Luxemburg Institute of Socio Economic Research and many others; Rose Mederios, Senior Statistician, from the Educational Services at StataCorp, came all the way from the USA to offer a presentation on Handkling Missing Data in Stata. This exceptional diversity amongst presentations and attendees led to a dense, high-quality conference with top-notch speakers. We were all the more excited to receive spontaneous tremendous feedback, as this was our very first edition: the verbatim hereafter speaks for itself.
For those wanting to catch up, you will find also the PDF of the presentations that were held during the day.

We won’t stop here. Next step? 2017. Paris. You have a whole year to work on the presentations you’d like to submit.
See you very soon, and thanks to all of you, Stata users!

Do you want to gain new perspectives on how to use Stata? Do you have insights that would enlighten colleagues in your field? Or you just want to meet fellow users and Stata Corp. developers?

Then join us in Bern for the first Swiss Stata Users Group meeting! The Institute of Social and Preventive Medicine, University of Bern, and Ritme, official partner of Stata for softwares and solutions in Switzerland, are glad to welcome you to this first Swiss edition. The event will take place on Thursday November 17th, 2016. It will be held in the premises of our academic partner at Haus der Universität (University of Bern, Schlösslistrasse 5, 3008 Bern).



Contributions are welcome on any aspect of the use of Stata, including focused empirical and theoretical analyses. The objective of this conference is to discuss the use of Stata across fields and backgrounds. A particular—but not exclusive—focus of this meeting will be on implementing reproducible research methods using Stata. The participation of early career scholars and postgraduate researchers is positively encouraged, nevertheless users of any affiliation and background are much welcome: economics, econometrics, finance, business, biostatistics, epidemiology, medicine and public health, behavioral sciences, social sciences etc. A presentation by a top-notch scholar representative of Stata Corp. will cover the implementation of new methods in Stata.



Submissions should include name and affiliation of the author, a title, and an informative abstract. The abstract should be no more than 200 words, and the presentations should be 20 minutes or shorter.

Please submit your abstract by email to

Presentation topics might include but are not limited to:

  • discussion of user-written Stata programs;
  • case studies of research or teaching using Stata;
  • reviews of analytical issues; and
  • surveys or critiques of Stata facilities in specific fields.

The submission deadline is August 19th, 2016. Ritme generously sponsors registration fee waivers for presenters.

The final program will be announced before the end of September 2016.


The scientific committee is responsible for the scientific program. The committee will referee abstracts and determine the schedule and the lengths of presentations.

Nouvelle mise à niveau Stata 14.1

Stata 14.1 est désormais disponible et n'engendre aucun frais supplémentaire pour les détenteurs de licences Stata 14. Pour obtenir la mise à niveau, saisissez "update query" et suivez les instructions.

Les nouvelles fonctionnalités de Stata 14.1

Le texte source de l'éditeur a été conservé afin d'éviter toute perte d'information.

Bayesian analysis
The new Bayesian analysis features introduced in Stata 14 now have dramatically improved performance and capabilities when working with latent variables and with panel and multilevel models. And, there is more in Bayesian analysis. See help whatsnew after updating.
The ICD-10 facilities now work with all codes from 2003 to 2015.
Multiple imputation
You can now add your own imputation methods to mi impute—Stata’s main engine for handling multiple imputation of missing data. It is simple. After updating, type help mi impute usermethod for documentation and examples.
Propensity-score matching
Propensity-score matching via teffects psmatch is now much faster for large datasets.
Those who use IRT (item response theory) will be glad to see the new diflogistic command that performs the logistic regression test for uniform and nonuniform differential item functioning (DIF). The Mantel–Haenszel test has improvements too. Type help difmh after updating.
More CIs
You can now get confidence intervals (CIs) for variances and standard deviations from the ci commands.
Mixed models
Small-sample denominator-degree-of-freedom adjustments such as Kenward–Roger and Satterthwaite can now be performed when estimating contrasts via the contrast command after estimating linear mixed models.
Exporting results to Excel®
The syntax for exporting estimation and other results to Excel spreadsheets has been dramatically simplified. You can also easily choose and export estimation and other results using the intuitive and functional dialog box.
MLEs of expressions
You can now predict expected means after mlexp—maximum likelihood estimation (MLE) of any expression you specify. This also implies that margins can be used after mlexp to estimate marginal and conditional effects, estimated marginal means, and predictive margins. mlexp also now supports linear constraints.
High DPI support
Under Windows, high DPI monitors are now better supported. A host of icon sizings keep your icons looking good when working at higher resolutions.

Censored outcomes

If you analyze data with Gaussian dependent variables that are censored, you will want to update to Stata 13.1. You can now do just about anything you want with such outcomes. Extensions of tobit and censored regression models include the following :

  • Selection models
  • Random effects and coefficients
  • Endogenous covariates
  • Treatments effects (ATEs)
  • Multivariate models
  • Unobserved components
  • Endogenous switching models

All of these models may be conbined with each other. For example, you can specifiy a tobit model with random effects, random coefficients, sample selection, and endogenous covariates. Moreover, the random coefficients can occur in both the outcome and selection models.

All of these features are implemented throught extensions to Stata's gsem (generalized SEM) command and graphical SEM Builder.


Power and sample size

The power command that was introduced in Stata 13 has new methods for analysis of ANOVA models :

  • One-way models
  • Two-way models
  • Repeated-measures models

Like other power methods, you can compute (1) sample size, (2) power, or (3) effect size. Compute any of the three given the other two.

You just tell power what you know, and it produces tables and graphs of what you want to know.

Stata 13.1 also introduces facilities to easily add your own new methods to the power command and produce tables and graphs of results automatically.

Power and sample size

Time series

Stata 13.1 also adds several new features for the analysis of univariate time series :

  •  IRFs (impulse—response functions) for ARIMA and ARFIMA models
  • Autocorrelation functions from ARIMA and ARFIMA models
  • Parametrics spectral densities for seasonal ARIMA models
  • Stability checks for ARIMA models

All of your favorite multivariate tools can now be applied to univariate models.

STATA et Windows 8


FAQ 1 : Est ce que Stata fonctionne avec Windows 8?

Stata fonctionne sans problème avec Windows 8 aussi bien sur les ordinateurs
 fixes, portables et les serveurs.

FAQ 2 : Est ce que Stata fonctionne avec Windows RT?

Windows RT est une version de Windows 8 pour tablette telle que
"Surface" de Microsoft.

Il existe deux versions de Windows 8 pour tablette :
Une version nommée simplement "Windows RT" qui fonctionne sur des tablettes
équipées de processeurs différents de l'architecture standard x86-64. Microsoft
n'a pas développé les outils et compilateurs nécessaires pour que Stata fonctionne
avec Windows RT.
Stata n'est actuellement pas compatible avec Windows RT.

Microsoft a planifié une version de Windows 8 Pro qui fonctionne sur tablette
telle que "Surface Pro" de Microsoft. Windows 8 Pro est conçu pour fonctionner
sur ces tablettes comme sur un ordinateur classique. Nous avons testé Stata sur
Windows 8 Pro sur des ordinateurs classiques et Stata fonctionne sans soucis
dans cet environnement.

Comme Microsoft n'a pas encore sortie officiellement sa tablette "Surface Pro",
nous ne pouvons pas encore certifier la compatibilité de Stata avec Windows 8 Pro.
