msaenet.nzv: Get Indices of Non-Zero Variables

Description

Get the indices of non-zero variables from msaenet model objects.

Usage

msaenet.nzv(object)

Arguments

object

An object of class msaenet produced by aenet, amnet, asnet, msaenet, msamnet, or msasnet.

Value

Indices vector of non-zero variables in the model.

Examples

dat = msaenet.sim.gaussian(n = 150, p = 500, rho = 0.6,
                           coef = rep(1, 5), snr = 2, p.train = 0.7,
                           seed = 1001)

msaenet.fit = msaenet(dat$x.tr, dat$y.tr,
                      alphas = seq(0.2, 0.8, 0.2),
                      nsteps = 3L, seed = 1003)

msaenet.nzv(msaenet.fit)

# coefficients of non-zero variables
coef(msaenet.fit)[msaenet.nzv(msaenet.fit)]
