Stata is my favorite statistical package. I’ve written two add-ons that are freely available
  • mkcorr, which produces tab-delimited output of descriptive statistics and correlations. To install, issue the command, "ssc install mkcorr, replace" from within Stata.
  • complogit, which provides tools to compare logit coefficients across groups. For more details, please see my 2007 SMJ paper. To install, issue the command, "ssc install complogit, replace" from within Stata.

I’ve also provided some commentary on my experiences with Stata, which might be especially relevant to doctoral students.
