sail-internal: Internal sail functions

In sahirbhatnagar/funshim: Sparse Additive Interaction Learning

Description

Internal sail helper functions

cbbPalette gives a Color Blind Palette

nonzero is to determine which coefficients are non-zero

check_col_0 is to check how many columns are 0 and is used in the fitting functions lspath

Usage

SoftThreshold(x, lambda)

l2norm(x)

cbbPalette

nonzero(beta, bystep = FALSE)

check_col_0(M)

Arguments

x	numeric value of a coefficient
lambda	tuning parameter value
beta	vector or 1 column matrix of regression coefficients
bystep	bystep = FALSE means which variables were ever nonzero. bystep = TRUE means which variables are nonzero for each step
M	is a matrix

Format

An object of class character of length 8.
