Materials for Stata and Runtime Revolution
from Kenneth L. Simons
The following technical tools may be useful to users of Stata, MetaCard,
and Revolution.
Stata
My list of Useful Stata Commands is an extensive reference that I created for my students.
The following ado files extend Stata's capabilities:

rcheck Check sensitivity (robustness) of results to alternative model specifications.

dfbeta3 Compute DFBETAs even after regress with robust/clustered SEs.

dummychk Check dummy (indicator) variables to ensure they are okay.

onetoone Assert a onetoone correspondence between values of variables.

globdist Distance between latitude & longitude coordinates.

circnum Count data points in a geographic radius of each point.

exlocs Create data points for extra geographic locations.

strlist List in compact form.

sthaz Smoothed hazard (transition/failure) rate plots.

hazplot Smoothed hazard (transition/failure) rate plots  alternative version
for discretetime data.

rencode Encode/decode and replace variable(s).

hammersley Hammersley sequences for nonrandom highefficiency sampling.

Runtime Revolution
Graph and Table Objects
I've created enhanced graph and table objects that Runtime Revolution
programmers can use to facilitate line graphs, scatter plots, tables, and
spreadsheets (latest update: 18 December 2006). These objects are easy
to paste into any Revolution project, and the file includes extensive documentation
and examples.
Download the objects in raw
or
zipped form. If you have any problem when downloading, try holding down the mouse button (try rightclicking if left doesn't work) and choosing to save as a file  in old browsers you may need to choose to save as the raw source (not text) when downloading.
