Say that you use SAS but wish to know how to do a particular command in
Stata. For example, you want to make a new variable and know you can use the
assignment statement (e.g. x = 1;) to
create a new variable in SAS, but what is the equivalent (or similar) command
in Stata (by the way, there are actually three similar Stata commands,
generate, replace, and egen). The table below shows you five
columns of information

This table is by no means complete, and it not intended to
be a complete and exhaustive reference. Instead, it is intended to be a short,
simple, sweet and handy reference for SAS users who are making the transition
to Stata. We also highly recommend
A Sample Stata Session
(via the Stata web site) which gives you a quick overview of using Stata as well
as seeing the [GS] Getting Started manual that accompanied your purchase of
Stata.

The first table shows SAS PROCs and the closest equivalent Stata command. The
subsequent table shows statements from DATA Steps.
