Computes masses and weights for epGPCA
.
computeMW(DATA, masses = NULL, weights = NULL)
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 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). |
