plmmr (version 4.2.3)

plot.plmm: Plot method for plmm class

Description

Plot method for plmm class

Usage

# S3 method for plmm
plot(x, alpha = 1, log.l = FALSE, shade = TRUE, col, ...)

Value

Nothing is returned; instead, a plot of the coefficient paths is drawn at each value of lambda (one 'path' for each coefficient).

Arguments

x

An object of class plmm

alpha

Tuning parameter for the Mnet estimator which controls the relative contributions from the MCP/SCAD penalty and the ridge, or L2 penalty. alpha=1 is equivalent to MCP/SCAD penalty, while alpha=0 would be equivalent to ridge regression. However, alpha=0 is not supported; alpha may be arbitrarily small, but not exactly 0.

log.l

Logical to indicate the plot should be returned on the natural log scale. Defaults to log.l = FALSE.

shade

Logical to indicate whether a local nonconvex region should be shaded. Defaults to TRUE.

col

Vector of colors for coefficient lines.

...

Additional arguments.

Examples

admix_design <- create_design(X = admix$X, y = admix$y)
fit <- plmm(design = admix_design)
plot(fit)
plot(fit, log.l = TRUE)
