computeMW: computeMW

In ExPosition: Exploratory Analysis with the Singular Value Decomposition

Description

Computes masses and weights for epGPCA.

Usage

computeMW(DATA, masses = NULL, weights = NULL)

Arguments

DATA	original data; will be used to compute masses and weights if none are provided.
masses	a vector or (diagonal) matrix of masses for the row items. If NULL (default), masses are computed as 1/# of rows
weights	a vector or (diagonal) matrix of weights for the column items. If NULL (default), weights are computed as 1/# of columns

Value

Returns a list with the following items:

M	a diagonal matrix of masses (if too large, a vector is returned).
W	a diagonal matrix of weights (if too large, a vector is returned).
