Confidence intervals for odds ratios
------------------------------------
.
   ^oddsrci^ [weight] [^if^ exp] [^in^ range] , ^c1(^cond1^) c2(^cond2^)^  [^lev^el^(^#^)^

^fweights^ are allowed; see help @weights@.

Description
-----------
.
^oddsrci^ creates a 2x2 table from a pair of Boolean conditions (^cond1^ and ^cond2^)
and computes the odds ratio and an associated confidence interval, using any of
four different estimation methods.  Conditions cond1 and cond2 are used to de-
fine temporary indicator variables, and the @tabulate@ command is then applied to
those variables to create the table.
.
The second syntax above displays a brief reminder of the first syntax.
.
.
Options
-------
.
^c1(^cond1^)^ provides a Boolean (true-false) expression that defines the rows of
    a 2x2 table.  [Not optional.]
.
^c2(^cond2^)^ provides another Boolean (true-false) expression that defines the
    columns of a 2x2 table.  [Not optional.]
.
^level(^#^)^ specifies the desired confidence level.  May be fractional and may be
    specified as a percentage (97.5) or a proportion (.9633).
.
^tabopt(^tab_options^)^ is used to pass options to the @tabulate@ command; only the
    ^nofreq^ option is unavailable.
.
^all, none^ choose among the following confidence intervals in the obvious way.
.
^agresti^ produces the "endpoint-adjusted, independence smoothed" confidence in-
    terval recommended by Agresti (1999).  [This is the default.]
.
^cornf^ yields the Cornfield confidence interval, as computed by @cci@.
.
^gart^ computes the Anscombe-Gart-Haldane confidence interval.
.
^woolf^ requests the Woolf confidence interval (same as in @cci@).
.
.
