ISRM and m-scale Plot
Description
Plot of m-scale and ISRM against scalar or vector values of biasing parameter K (Vinod, 1976 <doi:10.1080/01621459.1976.10480955>).
Usage
isrm.plot(x, ...)Arguments
x |
An object of class "lmridge". |
... |
Not presently used in this implementation. |
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.
Value
Nothing returned
