variance: Variance and confidence intervals of indicators on social exclusion and poverty

Description

Compute variance and confidence interval estimates of indicators on social exclusion and poverty.

Usage

variance(inc, weights = NULL, years = NULL,
    breakdown = NULL, design = NULL, cluster = NULL,
    data = NULL, indicator, alpha = 0.05, na.rm = FALSE,
    type = "bootstrap", gender = NULL, method = NULL, ...)

Arguments

inc

either a numeric vector giving the equivalized disposable income, or (if data is not NULL) a character string, an integer or a logical vector specifying the corresponding column of data.

weights

optional; either a numeric vector giving the personal sample weights, or (if data is not NULL) a character string, an integer or a logical vector specifying the corresponding column of data.

years

optional; either a numeric vector giving the different years of the survey, or (if data is not NULL) a character string, an integer or a logical vector specifying the corresponding column of data. If sup

breakdown

optional; either a numeric vector giving different domains, or (if data is not NULL) a character string, an integer or a logical vector specifying the corresponding column of data. If supplied, the value

design

optional; either an integer vector or factor giving different strata for stratified sampling designs, or (if data is not NULL) a character string, an integer or a logical vector specifying the corresponding column of

cluster

optional; either an integer vector or factor giving different clusters for cluster sampling designs, or (if data is not NULL) a character string, an integer or a logical vector specifying the corresponding column of <

data

an optional data.frame.

indicator

an object inheriting from the class "indicator" that contains the point estimates of the indicator (see arpr, qsr,

alpha

a numeric value giving the significance level to be used for computing the confidence interval(s) (i.e., the confidence level is $1 -$alpha), or NULL.

na.rm

a logical indicating whether missing values should be removed.

type

a character string specifying the type of variance estimation to be used. Currently, only "bootstrap" is implemented for variance estimation based on bootstrap resampling (see bootVar

gender

either a numeric vector giving the gender, or (if data is not NULL) a character string, an integer or a logical vector specifying the corresponding column of data.

method

a character string specifying the method to be used (only for gpg). Possible values are "mean" for the mean, and "median" for the median. If weights are provided, the weight

...

additional arguments to be passed to bootVar.

Value

• An object of the same class as indicator is returned. See arpr, qsr, rmpg or gini for details on the components.

Details

This is a wrapper function for computing variance and confidence interval estimates of indicators on social exclusion and poverty.

Examples

data(eusilc)
a <- arpr("eqIncome", weights = "rb050", data = eusilc)

## naive bootstrap
variance("eqIncome", weights = "rb050", design = "db040",
    data = eusilc, indicator = a, R = 50,
    bootType = "naive", seed = 123)

## bootstrap with calibration
variance("eqIncome", weights = "rb050", design = "db040",
    data = eusilc, indicator = a, R = 50,
    X = calibVars(eusilc$db040), seed = 123)
