Re: st: Binomial regression
A couple of points that have not yet been mentioned:
Binomial regression for risk differences is available for any linear
model using
-binreg, rd-. This is more flexible than either -cs- or -somersd-
It would be useful if Stata extended the transformations available
for displaying results with -lincom-. At the moment, we have 2 options
(untransformed & exponential) and six labels (5 being for exponential form).
An -inverse- transformation, specifically for NNT (number needed to
treat ) would be useful for those who could use it with discretion.
An -inverse with sign change- would also be useful for NNH (number
needed to harm).
A warning would be needed that for non-significant results,
the interval can be very difficult to interpret.
