get_rif_variance {rifreg}

Estimate RIF of variance

Description

Function to estimate the recentered influence function (RIF) of the variance of a weighted distribution of a dependent variable.

Usage

get_rif_variance(dep_var, weights)

Arguments

dep_var

dependent variable of a distributional function. Discrete or continuous numeric vector.

weights

numeric vector of non-negative observation weights, hence of same length as dep_var. The default (NULL) is equivalent to weights = rep(1, length(dep_var)).

Value

A data frame with one column containing the RIF of the variance for each observation and one column containing the weights.

Examples

dep_var <- c(1, 3, 9, 16, 3, 7, 4, 9)
weights <- c(2, 1, 3, 4, 4, 1, 6, 3)
get_rif_variance(dep_var, weights = weights)
