svyarpr: At-risk-of-poverty rate

Description

Estimate the proportion of persons with income below the at-risk-of-poverty threshold.

Usage

svyarpr(formula, design, ...)
# S3 method for survey.design
svyarpr(formula, design, quantiles = 0.5, percent = 0.6, na.rm = FALSE, ...)
# S3 method for svyrep.design
svyarpr(formula, design, quantiles = 0.5, percent = 0.6, na.rm = FALSE, ...)
# S3 method for DBIsvydesign
svyarpr(formula, design, ...)

Arguments

formula

a formula specifying the income variable

design

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

...

arguments passed on to `svyarpt`

quantiles

income quantile, usually .50 (median)

percent

fraction of the quantile, usually .60

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.
