StataCorp‘s flagship statistical software, Stata, has long been the preferred tool for data analysis in economics, sociology, political science, epidemiology, biostatistics, and many other fields. Stata 18 continues this legacy, offering an array of new features that enhance everything from data management to reporting and Python integration.

Stata/MP leverages multi-core processing to run analyses significantly faster than other editions. For a logistic regression with 10 million observations, Stata/MP2 runs nearly twice as fast as Stata/SE, while Stata/MP4 is almost four times faster. Stata 18

When working with large panel data (e.g., millions of observations), controlling for individual-level characteristics is crucial. The enhanced HDFE tools in Stata 18 (e.g., reghdfe ) make these estimations significantly faster and more accurate, overcoming traditional memory and computational limitations.

Group sequential designs allow calculation of efficacy and futility stopping bounds for clinical trials, along with required sample sizes for interim and final analyses when testing proportions, means, or survivor functions. The RERI command supports interaction analysis for epidemiological studies. millions of observations)

While Stata 18 is no longer the very latest major version—StataNow (version 19.5) was released in 2025, followed by Stata 19 in April 2025—it remains a powerful and widely used platform that introduced many foundational features now considered indispensable in modern data analysis. StataCorp also continues to release minor updates; for instance, StataMP 18.5 brought further optimizations and new functionality.
