Plot the coefficient path of SPLS regression
Provide the coefficient path plot of SPLS regression as a function of the number of hidden components (K) when eta is fixed.
## S3 method for class 'spls' plot( x, yvar=c(1:ncol(x$y)), ... )
x |
A fitted SPLS object. |
yvar |
Index vector of responses to be plotted. |
... |
Other parameters to be passed through to generic |
plot.spls
provides the coefficient path plot of SPLS fits.
The plot shows how estimated coefficients change
as a function of the number of hidden components (K
),
when eta
is fixed at the value used by the original SPLS fit.
