Institutional research

Institutional researchers rely on Stata for its breadth, accuracy, reproducibility, and ease of use. Whether you are evaluating predictors of student retention, analyzing faculty turnover rates, or studying the effects of tuition policies, Stata provides all the data manipulation, visualization, statistics, and reporting tools you need to complete your analyses.




Features for institutional research

Importing and manipulating data
Scrape data from the web, import them from standard formats, or pull them in via ODBC and SQL. Match-merge, append, reshape, transpose, sort, filter. Stata handles Unicode, BLOBs, regular expressions, and more, whether working with hundreds of thousands or even billions of data points. Read more.

Visualization
Create graphs and customize them programmatically or interactively with the Graph Editor. Edits can even be recorded and "replayed" on other graphs for reproducibility. Export to industry standard formats suitable for web (SVG, PNG) or print (PDF, EPS, PS). Read more.

Dynamic document generation
Use Markdown to create HTML files with embedded Stata code, output, and graphs. Automate Word, PDF, or Excel reports with both high-level export capabilities and low-level, fine-grained programmatic access to automate production of the documents your team needs. Read more about Markdown, about Word Documents, about PDF documents, or about Excel.

Linear, binary, and count regressions
Fit classical linear regression models of the relationship between a continuous outcome, such as college algebra grade, and the determinants of the grade, such as SAT math score and high school GPA. If your response is binary (for example, completed degree or not), ordinal (education level), count (number of students), or categorical (business, engineering, liberal arts, or education major), don't worry. ... Stata has maximum likelihood estimators—logistic, ordered logistic, Poisson, multinomial logit, and many others—that estimate the relationship between such outcomes and their determinants. A vast array of tools is available after fitting such models. Predict outcomes and their confidence intervals. Test equality of parameters. Compute linear and nonlinear combinations of parameters. And much more. Read more

Multilevel mixed-effects models
Whether the groupings in your data arise in a nested fashion (students nested in colleges and colleges nested in universities) or in a nonnested fashion (colleges crossed with student's home state), you can fit a multilevel model to account for the lack of independence within these groups. ... Fit models for continuous, binary, count, ordinal, and survival outcomes. Estimate variances of random intercepts and random coefficients. Compute intraclass correlations. Predict random effects. Estimate relationships that are population averaged over the random effects. And much more. Read more

Panel data
Take full advantage of the extra information that panel data provide while simultaneously handling the peculiarities of panel data. Study the time-invariant features within each panel, the relationships across panels, ... and how outcomes of interest change over time. Fit linear models or nonlinear models for binary, count, ordinal, censored, or survival outcomes with fixed-effects, random-effects, or population-averaged estimators. Fit dynamic models or models with endogeneity. And much more. Read more

Structural equation modeling (SEM)
Estimate mediation effects, analyze the relationship between an unobserved latent concept such as a quantitative reasoning and the observed variables that measure quantitative reasoning, or fit a model with complex relationships among both latent and observed variables. ... Fit models with continuous, binary, count, and ordinal outcomes. Even fit hierarchical models with groups of correlated observations such as students within the same college. Evaluate model fit. Compute indirect and total effects. Fit models by drawing a path diagram or using the straightforward command syntax. And much more. Read more

Causal inference
Estimate experimental-style causal effects from observational data. With Stata's treatment-effect estimators, we can use a potential-outcomes (counterfactuals) framework to estimate, for instance, the effect of being a first-generation student on retention or the effect of taking developmental courses on graduation rates. ... Fit models for continuous, binary, count, fractional, and survival outcomes with binary or multivalued treatments using propensity-score matching, inverse-probability weighting (IPW), nearest-neighbor matching, regression adjustment, or doubly robust estimators. If the assignment to a treatment is not independent of the outcome, you can use an endogenous treatment-effects estimator. And much more. Read more

Survival analysis
Analyze duration outcome—outcomes measuring the time to an event such as graduation—using Stata's specialized tools for survival analysis. Account for the complications inherent in survival data, such as sometimes not observing the event (censoring), individuals entering the study at differing times (delayed entry),... and individuals who are not continuously observed throughout the study (gaps). You can estimate and plot the probability of survival over time. Or model survival as a function of covariates using Cox, Weibull, lognormal, and other regression models. Predict hazard ratios, mean survival time, and survival probabilities. Do you have groups of individuals in your study? Adjust for within-group correlation with a random-effects or shared frailty model. And much more. Read more

Multivariate methods
Use multivariate analyses to evaluate relationships among variables from many different perspectives. Perform multivariate tests of means, or fit multivariate regression and MANOVA models. ... Explore relationships between two sets of variables, such as aptitude measurements and achievement measurements using canonical correlation. Examine the number and structure of latent concepts underlying a set of variables using exploratory factor analysis. Or use principal component analysis to find underlying structure or to reduce the number of variables used in a subsequent analysis. Discover groupings of observations in your data using cluster analysis. If you have known groups in your data, describe differences between them using discriminant analysis. And much more. Read more

Bayesian analysis
Fit Bayesian regression models using one of the Markov chain Monte Carlo (MCMC) methods. You can choose from a variety of supported models or even program your own. Extensive graphical tools are available to check convergence visually. ... Compute posterior mean estimates and credible intervals for model parameters and functions of model parameters. You can perform both interval- and model-based hypothesis testing. Compare models using Bayes factors. And much more. Read more
