svygpg: Linearization of the gender pay (wage) gap

In convey: Income Concentration Analysis with Complex Survey Samples

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 class 'survey.design'
svygpg(formula, design, sex, na.rm = FALSE, ...)

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

## S3 method for class '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?

Details

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

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.
