AF: OPHI counting approach

Description

The function implements in a single call the OPHI counting approach. The implementation is limited to ordinal attributes.

Usage

AF(y, ...)
# S3 method for default
AF(y, z, w=rep(1, ncol(y)), k=sum(w), freq=rep(1, nrow(y)), ...)
# S3 method for wprof
AF(y, ...)

Arguments

y

matrix of profiles, it can be substituted by an object of class wprof.

z

vector of attribute cutoffs.

w

variables weights.

k

overall cutoff.

freq

profiles frequencies, if y is an object of class wprof this argument can be omitted.

…

any of the above.

Value

An object of S3 class ophi containing all the outputs related to the OPHI counting approach. The object is a list with the following arguments

y

matrix of profiles,

freq

profile frequencies,

d

number of variables

n

number of observations (sun of frequencies),

z

vector of cutoffs,

k

overall cutoff,

rho

function comparing profiles with the vector of cutoffs,

rho_k

function comparing profiles with the overall cutoff, by weighting variables,

g0

profile-variable matrix reporting the output of function rho,

c

censored vector of deprivation counts,

Z_k

a boolean vector identifying deprived profiles, according to specified cutoffs,

q

number of poor statstical units in the population,

H

headcount ratio, i.e. of q/n, where n is the number of statistical units in the population,

A

average deprivation share,

M0

adjusted headcount ratio.

# NOT RUN {
vl <- c(2, 3, 3, 2)
prof <- var2prof(varlen = vl)

res <- AF(prof, z = c(1, 2, 1, 1), k = 1)
