Syntax
------

rrisk , cmd( logistic regression command here )

The rrisk command computes relative risks for 0/1 predictor
variables given in the logistic regression command in the
cmd( ) option.  Variables which are not coded 0/1 are overlooked
for this computation. 

For a given variable (say X) the relative risk is computed
by obtaining the predicted probability that Y=1 when X is 1
and the predicted probabily that Y=1 when X=0.  These
predicted probabilities are divided and then summarized,
yielding the relative risk.

Examples
--------

use https://stats.idre.ucla.edu/stat/stata/notes/hsb2, clear
gen goodread = read > 60
gen public = schtyp == 1

* example 1, just get rr
rrisk, cmd(logistic goodread female public write)

* example 2, use "bs" to get rr for female
bs "rrisk, cmd(logistic goodread female public write)" "r(rr_female)", reps(100
> 0)

* example 3, use "bs" to get rr for female and public
bs "rrisk, cmd(logistic goodread female public write)" "r(rr_female) r(rr_publi
> c)", reps(1000)
