se.meanratio2: Computes the standard error for a 2-group log mean ratio

In dgbonett/vcmeta: Varying Coefficient Meta-Analysis

Computes the standard error for a 2-group log mean ratio

Description

This function computes the standard error of a 2-group log mean ratio using the estimated means, estimated standard deviations, and sample sizes. The log mean 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 application where compatible mean ratios from a combination of 2-group and paired-samples experiments are used in the meta-analysis. Equality of variances is not assumed.

Usage

se.meanratio2(m1, m2, sd1, sd2, n1, n2)

Arguments

m1	estimated mean for group 1
m2	estimated mean for group 2
sd1	estimated standard deviation for group 1
sd2	estimated standard deviation for group 2
n1	sample size for group 1
n2	sample size for group 2

Value

Returns a one-row matrix:

• Estimate - estimated log mean ratio

• SE - standard error
