Glog optimisation — glog_opt_plot • structToolbox

A plot of the sum of squares error (SSE) vs different values of lambda for the glog transform. The indicated optimum value for lambda minimises the SSE.

Usage

glog_opt_plot(plot_grid = 100, ...)

Arguments

plot_grid: (numeric) The default is 100.
...: Additional slots and values passed to struct_class.

Value

A glog_opt_plot object. This object has no output slots. See chart_plot in the struct package to plot this chart object.

Details

This object makes use of functionality from the following packages:

pmp

Inheritance

A glog_opt_plot object inherits the following struct classes:

[glog_opt_plot] >> [chart] >> [struct_class]
