hellingerNorm: Hellinger version of CA preprocessing

In ExPosition: Exploratory Analysis with the Singular Value Decomposition

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	Deviations of row profiles from rowCenter.
