contingencyWt: Weighted contingency coefficients

Description

Compute (weighted) pairwise contingency coefficients.

Usage

contingencyWt(x, ...)

Value

For the default method, the (weighted) contingency coefficient of x and y.

For the matrix and data.frame method, a matrix of (weighted) pairwise contingency coefficients for all combinations of columns. Elements below the diagonal are NA.

Arguments

x

for the default method, a vector that can be interpreted as factor. For the matrix and data.frame methods, the columns should be interpretable as factors.

...

for the generic function, arguments to be passed down to the methods, otherwise ignored.

Details

The function tableWt is used for the computation of the corresponding pairwise contingency tables. The following methods are implemented:

• contingencyWt.default(x, y, weights = NULL, ...)

• contingencyWt.matrix(x, weights = NULL, ...)

• contingencyWt.data.frame(x, weights = NULL, ...)

Additional parameters are:

• y: a vector that can be interpreted as factor (for the default method)

• weights: an optional numeric vector containing sample weights

Examples

data(eusilcS)

## default method
contingencyWt(eusilcS$pl030, eusilcS$pb220a, weights = eusilcS$rb050)

## data.frame method
basic <- c("age", "rb090", "hsize", "pl030", "pb220a")
contingencyWt(eusilcS[, basic], weights = eusilcS$rb050)
