frobenius_norm_funct_multiv: Functional multivariate Frobenius norm

Description

Computes the functional multivariate Frobenius norm.

Usage

frobenius_norm_funct_multiv(m, PM)

Arguments

m

Data matrix with the residuals. This matrix has the same dimensions as the original data matrix.

PM

Penalty matrix obtained with eval.penalty.

Value

Real number.

Details

Residuals are vectors. If there are p variables (columns), for every observation there is a residual that there is a p-dimensional vector. If there are n observations, the residuals are an n times p matrix.
