plmmr (version 4.3.0)

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 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)
