svygpg: Linearization of the gender pay (wage) gap

Description

Estimate the difference between the average gross hourly earnings of men and women expressed as a percentage of the average gross hourly earnings of men.

Usage

svygpg(formula, design, ...)
# S3 method for survey.design
svygpg(formula, design, sex, na.rm = FALSE, ...)
# S3 method for svyrep.design
svygpg(formula, design, sex, na.rm = FALSE, ...)
# S3 method for DBIsvydesign
svygpg(formula, design, sex, ...)

Arguments

formula

a formula specifying the gross hourly earnings variable

design

a design object of class survey.design or class svyrep.design from the survey library.

...

future expansion

sex

formula with a factor with labels 'male' and 'female'

na.rm

Should cases with missing values be dropped?

Value

Object of class "cvystat", which are vectors with a "var" attribute giving the variance and a "statistic" attribute giving the name of the statistic.

Details

you must run the convey_prep function on your survey design object immediately after creating it with the svydesign or svrepdesign function.
