Meta – Analysis

With Stata’s new meta-analysis suite, you can easily summarize results from multiple studies.

  • Estimate an overall effect size
  • Perform random-effects, fixed-effects, or common-effect meta-analysis
  • Display results in a forest plot
  • Analyze subgroups
  • Perform meta-regression
  • Explore small-study effects
  • Evaluate publication bias
  • Perform cumulative meta-analysis

Choice Models

With Stata’s new and unique choice-model analysis features, you can truly interpret the results of your choice model.

What proportion of travelers are expected to choose air travel?

How does each additional $10,000 of income change the probability of traveling by air?

Wait times at the airport increase by 30 minutes. How does this affect the probability of traveling by air? By train? By bus? By car?

Nonparametric Series Regression

Agnostic about functional form? Poisson or negative binomial? Cubic or quadratic on a covariate?

No problem.

With nonparametric regression, you can explore the response surface, estimate population-averaged effects, perform tests, and obtain confidence intervals.

Frames — Multiple Datasets In Memory

  • Load datasets simultaneously into frames.
  • Link related frames.
  • Multitask.
  • Record results in another frame.
  • Make code run faster.
