icdf: Linearization of the cumulative distribution function (cdf) of a variable

Description

Computes the linearized variable of the cdf function in a point.

Usage

icdf(formula, design, x, na.rm = FALSE, ...)

Arguments

formula

a formula specifying the income variable

design

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

x

the point where the cdf is calculated

na.rm

Should cases with missing values be dropped?

...

future expansion

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.
