## computeMW

### 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).
