computeMW function

computeMW

Computes masses and weights for epGPCA.

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

Returns

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).
