Hello to All,

I would like to know if there is any *automatic* way to produce
multinomial confidence intervals in SAS. If, for instance, I have a
question which offers 4 different possible choices of answer, I would
like to compute the proportion of subjects who chose each option, as
well as a CI associated with that proportion.

The FREQ procedure will output the desired CI when the BINOMIAL option
is specified in the TABLES statement, but this is only done for 1 level
of the multinomial variable, not all of them.

If no such option exists, Leslie Daly posted a macro to obtain binomial
confidence intervals in 1995 (link below) and I was wondering if this
could be used. Here is the link to the original post:

Thank you,
