se.propratio2: Computes the estimate and standard error for a 2-group log proportion ratio
Description
Computes the Price-Bonett standard error of a 2-group proportion ratio using
the frequency count and sample size for each group. The log proportion ratio
and standard error output from this function can be used as input in the
meta.ave.gen.log function in applications where compatible
proportion ratios from a combination of 2-group and paired-samples studies
are used in the meta-analysis. If the proportions in each group are small
(less than .1), proportion ratios may be compatible with odds ratios and
then the meta.ave.gen.log function could be used to
meta-analyze any combination of log proportion ratios and log odds ratios.
Usage
se.propratio2(f1, f2, n1, n2)
Value
Returns a one-row matrix:
Estimate - estimated log proportion ratio
SE - standard error
Arguments
f1
number of participants in group 1 who have the outcome
f2
number of participants in group 2 who have the outcome
