Stata's expertise lies in the analysis of time based data. Stata provides not only the basic time series models like ARIMA but even the multivariate equivalents (VAR/VEC-Models) as well. Further you are able to model volatility using GARCH-models in Stata. Kaplan-Meier-curves are the way to analyse survival times, while mixed models help to analyse panel data. A mighty scripting language completes the package.

Stata produces all kinds of classical statistics. You can use it for descriptive statistics, hypothesis testing and visualization of data. Typically Stata is used in research and development. The large amount of different statistical methods helps scientists in all fields of applications (Social science, econometrics, epidimiology, medical research).

No matter if you are a student or a senior researcher, there is always the right version of STATA available: Stata/IC, Stat/ SE and Stata/MP

Arguments for Stata:

  • Used in research and development
  • Wide range of statistical and graphical methods
  • Comprehensive statistical software
  • Flexible and especially powerful for analysis of time series
  • Easy to learn but mighty scripting language

Discover and understand the unobserved groupings in your data. Use LCA's model-based classification to find out

  • how many groups you have,
  • who is in those groups, and
  • what makes those groups distinct.

Interval-censored survival models

Fit any of Stata's six parametric survival models to interval-censored data. All the usual survival features are supported: stratified estimation, robust and clustered SEs, survey data, graphs, and more.

Mixed logit models: Advanced choice modeling

Do you walk to work, ride a bus, or drive your car? Which of three insurance plans do you buy? Which political party do you vote for?

We make dozens of choices every day. Researchers have access to gaggles of data about those choices. Mixed logit introduces random effects into choice modeling and thereby relaxes the IIA assumption and increases model flexibility.

Bayesian multilevel models

Graph

Small number of groups?
Many hierarchical levels?
Prefer making probability statements?

Consider Bayesian multilevel modeling.

 
 

Threshold regression

graph

Your time-series regression may change parameters at some point in time or at multiple points in time. The activity of foraging animals might follow a completely different pattern at temperatures above some threshold. You may not know the value of that threshold. Finding such thresholds and estimating the parameters within the regimes is what threshold regression does.

 
 

Panel-data tobit with random coefficients

graph

Stata has long had estimators for random effects (random intercepts) in panel data.

 

Search, browse, and import FRED data

graph

The St. Louis Federal Reserve makes available over 470,000 U.S. and international economic and financial time series. You can now easily search, browse, and import these data.

 
 

Multilevel regression for interval-measured outcomes

Incomes are sometimes recorded in groupings, as are people's weights, insect counts, grade-point averages, and hundreds of other measures. Often we have repeated measurements for individuals, or schools, or orchards, etc. So ... we need multilevel regression for interval-measured (interval-censored) outcomes.

 
 

Multilevel tobit regression for censored outcomes

  • Left-censoring, right-censoring, both
  • Censoring that varies by observation
  • Make inferences about either the uncensored or the censored outcome
  • Robust and clustered SEs
  • Support for survey data

Poisson models with sample selection

Counts are common. How many:

Fish did you catch?
Accidents occurred?
Patents does a firm generate?

Outcomes are not always seen.

Folks evade the game warden.
Accidents are not always reported.
Some firms prefer trade secrets to patents.

So you need Poisson models with sample selection.
