Report: Stata 18 Feature Overview and Analysis

Date: October 26, 2023 Subject: Analysis of New Features and Enhancements in Stata 18 Prepared For: Research Team / Data Management Unit

Bayesian Analysis

  • Bayesian Multilevel Models: bayesmh now supports hierarchical models with random intercepts/slopes.
  • Bayesian Model Averaging (BMA): New bmareg for linear and logistic regression, accounting for model uncertainty.
  • Posterior predictive checking and improved convergence diagnostics.

7.2 Assertions

assert inrange(mpg, 10, 50)
assert !missing(price) if foreign==1

Q: Can I open Stata 17 datasets in Stata 18?

Yes. Stata’s .dta format is backward compatible. However, saving a dataset in Stata 18 with new attributes (e.g., Bayesian posterior samples) may not open in Stata 17. Stata 18

Limitations

  • Cost and licensing: Stata is commercial software with per-seat licensing; this can be a barrier compared with free alternatives.
  • Learning curve for advanced features: While basic commands are accessible, mastering advanced modeling, programming, or integration with other languages requires time.
  • Less flexible than general-purpose languages: For highly customized data science pipelines, languages like Python or R may offer more libraries and fluid scripting capabilities.
