In dgbonett/vcmeta: Varying Coefficient Meta-Analysis

Confidence interval for a linear contrast of proportion differences in paired-samples studies

Description

Computes the estimate, standard error, and adjusted Wald confidence interval for a linear contrast of paired-samples proportion differences from two or more studies.

Usage

meta.lc.prop.ps(alpha, f11, f12, f21, f22, v)

Arguments

alpha	alpha level for 1-alpha confidence
f11	vector of frequency counts in cell 1,1
f12	vector of frequency counts in cell 1,2
f21	vector of frequency counts in cell 2,1
f22	vector of frequency counts in cell 2,2
v	vector of contrast coefficients

Value

Returns 1-row matrix with the following columns:

• Estimate - estimated linear contrast

• SE - standard error

• LL - lower limit of the adjusted Wald confidence interval

• UL - upper limit of the adjusted Wald confidence interval
