transform_z: Computes indicator and standardized residual matrices

Description

This function returns the indicator (or dummy) matrix and the standardized residual matrix of a given data matrix.

Usage

transform_z(data,is.weight=TRUE,is.exact=TRUE,r=1,c=1)

Arguments

data

Matrix or data frame

is.weight

Logical indicating whether computations are based on user-defined weights/masses

is.exact

Logical indicating whether the computations mimic the case when 'exact' or 'live' MCA is applied

r

Row masses; applicable only when is.weight = TRUE

c

Column masses; applicable only when is.weight = TRUE

Value

• dZ
  Indicator matrix
• Q
  Number of variables
• J
  Number of variable attributes
• r
  Row masses
• c
  Column masses
• SZ
  Standardized residual matrix

Examples

data(women, package="idm")
outZ = transform_z(women[,c(1:7)],is.weight=FALSE)
