lmridge (version 1.2.2)

isrm.plot: ISRM and m-scale Plot

Description

Plot of m-scale and ISRM against scalar or vector values of biasing parameter \(K\) (Vinod, 1976 <tools:::Rd_expr_doi("10.1080/01621459.1976.10480955")>).

Usage

isrm.plot(x, ...)

Value

Nothing returned

Arguments

x

An object of class "lmridge".

...

Not presently used in this implementation.

Author

Details

The isrm.plot function can be used to plot the values of m-scale and ISRM against given list (scalar or vector values) of biasing parameter \(K\) as argument to lmridge. It can be helpful for the optimal selection of the biasing parameter \(K\).
