Software Update: Stata 15.0

Stata is a software package for statistics and is widely used in economics, sociology and epidemiology corners. It can manage the data, perform statistical analyses, simulate and analyze regressions. For more information, we refer you to this page. The development team has released version 15.0 with the following announcement:

Stata 15 announced, available now

We announced Stata 15 today. It’s a big deal because this is Stata’s biggest release ever.

I posted to Statist this morning and listed sixteen of the most important new features. Here on the blog I will say more about them, and you can learn even more by visiting our website and seeing the Stata 15 features page.

I go into depth below on the sixteen highlighted features. They are (click to jump)

• Extended regression models
• Latent class analysis (LCA)
• Bayesian prefix command
• Linearized dynamic stochastic general equilibrium (DSGE) models
• Dynamic Markdown documents for the web
• Nonlinear mixed-effects models
• Spatial autoregressive models (SAR)
• Interval-censored parametric survival-time models
• finite mixture models (FMMs)
• mixed log models
• Nonparametric regression
• Power analysis for cluster randomized designs and regression models
• Word and PDF documents
• Graph color transparency/opacity
• ICD-10-CM/PCS support
• Federal Reserve Economic Data (FRED) support
• And more

The sixteen features listed above certainly important ones, but there are others worthy of mention. More come readily to mind:

• Bayesian multilevel models
• Threshold regression
• Panel-data tobit with random coefficients
• Multilevel regression for interval-measured outcomes
• Multilevel tobit regression for censored outcomes
• Panel data co-integration tests
• Tests for multiple breaks in time series
• Multiple-group generalized SEM
• Heteroskedastic linear regression
• Poisson models with Heckman-style sample selection
• Panel-data nonlinear models with random coefficients
• Bayesian panel-data models Panel-data interval regression with random coefficients
• SVG export
• Bayesian survival models
• Zero-inflated ordered probit
• Add your own power and sample-size methods
• Bayesian sample selection models
• Stata in Swedish
• Improvements to the Do file Editor
• Stream random number generator
• Improvements for Java plugins
• More parallelization in Stata/MP
