In dgbonett/vcmeta: Varying Coefficient Meta-Analysis

Computes the estimate and standard error for a 2-group proportion difference

Description

This function computes the Agresti-Caffo standard error of a 2-group proportion difference using the frequency counts and sample sizes. The effect size estimate and standard error output from this function can be used as input in the meta.ave.gen, meta.lc.gen, and meta.lm.gen functions in applications where compatible proportion differences from a combination of 2-group and paired-samples studies are used in the meta-analysis.

Usage

se.prop2(f1, f2, n1, n2)

Arguments

f1	number of participants in group 1 who have the outcome
f2	number of participants in group 2 who have the outcome
n1	sample size for group 1
n2	sample size for group 2

Value

Returns a one-row matrix:

• Estimate - estimated proportion difference

• SE - standard error
