Mean squared error of factor model

Same as the evaluate S4 method for the nmf class, but allows one to input the `w`, `d`, `h`, and `data` independently.

Usage

mse(w, d = NULL, h, data, mask = NULL, missing_only = FALSE, ...)

Arguments

w

feature factor matrix (features as rows)

d

scaling diagonal vector (if applicable)

h

sample factor matrix (samples as columns)

...
