Stata is a widely used, general-purpose statistical software package. It is generally used in the fields of econometrics, sociology, biology and epidemiology. In contrast to SPSS, Stata emphasizes a command-line interface and the ability to create user-defined scripts in order to produce inferential statistical models. Its functionality is much more diverse however in comparison to SPSS, but consequently is more difficult to use. It has many more types of regression models, including Logit Regressions, Multinomial Regressions, Ordinal Logit Regressions as well as tests numerous for heteroscedasticity such as the Breusch-Pagan test.
