filter_nonzero_bases {plsmmLasso}

Filter bases functions

Description

The filter_nonzero_bases function filters out bases functions that are essentially zero. Bases functions with a sum of absolute values less than a threshold (10^{-10}) are considered as essentially zero and are filtered out.

Usage

filter_nonzero_bases(bases)

Arguments

bases

A matrix containing the bases functions.

Value

A list with the following components:

filtered_bases

A matrix containing the filtered bases functions, removing those that are essentially zero.

selected_bases

A vector containing the indices of the selected bases functions after filtering.

Examples

bases <- matrix(c(0, 0.1, 0.2, 0, 0, 0.3, 0, 0, 0), nrow = 3)
filtered_bases <- filter_nonzero_bases(bases)
