Relative/Percent Difference in Means

Calculate the relative difference in means with standard error based on the delta method.

Usage

reldif_means(x, y, scale = 100)

Arguments

x

A numeric vector

y

A numeric vector

scale

A numeric value to scale the output. scale=100 produces percentages and scale=1 produces proportions.

Value

data.frame

Details

For two samples x and y, relative difference = (mean(y) - mean(x)) / mean(x)
