st: New package -powersim- available from SSC

[Joerg Luedicke <joerg.luedicke@gmail.com>]

Hi everyone,

Thanks to Kit Baum, the -powersim- package is now available from the
SSC archive.
Type -ssc install powersim- to install it. The package also includes a little
tutorial as an ancillary file, type -net get powersim- to copy it into
your current directory.


Package description:

         powersim exploits the flexibility of a simulation-based
      approach to the analysis of statistical power by providing a
      facility for automated power simulations in the context of linear
      and generalized linear regression models. The package supports a
      wide variety of uni- and multivariate covariate distributions and
      all family and link choices that are implemented in Stata's glm
      command (as of version 13). powersim simulates statistical power
      with respect to a specified data generating model in a point null
      hypothesis significance testing framework, but can also be used
      for quickly generating synthetic datasets or for performing
      simple Monte Carlo experiments in a regression context.

I have presented the package at the last Stata Conference in New
Orleans, slides are available here:

that is shown in -help powersim-.
