hellingerNorm {ExPosition}

Hellinger version of CA preprocessing

Description

Performs all steps required for Hellinger form of CA processing (row profile approach).

Usage

hellingerNorm(X, X_dimensions, colTotal, rowTotal, grandTotal, 
	weights = NULL, masses = NULL)

Arguments

X

Data matrix

X_dimensions

The dimensions of X in a vector of length 2 (rows, columns). See dim

colTotal

Vector of column sums.

rowTotal

Vector of row sums.

grandTotal

Grand total of X

weights

Optional weights to include for the columns.

masses

Optional masses to include for the rows.

Value

rowCenter

The barycenter of X.

masses

Masses to be used for the GSVD.

weights

Weights to be used for the GSVD.

rowProfiles

The row profiles of X.

deviations
