pamr.predictmany | R Documentation |
A function giving prediction information for many threshold values,
from a nearest shrunken centroid fit.
Description
A function giving prediction information for many threshold values,
from a nearest shrunken centroid fit
Usage
pamr.predictmany(fit, newx, threshold = fit$threshold, prior = fit$prior,
threshold.scale = fit$threshold.scale, ...)
Arguments
fit |
The result of a call to pamr.train
|
newx |
Matrix of features at which predictions are to be made
|
threshold |
The desired threshold values
|
prior |
Prior probabilities for each class. Default is that
specified in "fit"
|
threshold.scale |
Additional scaling factors to be applied
to the thresholds. Vector of length equal to the number of
classes.
Default is that
specified in "fit".
|
... |
Additional arguments to be passed to pamr.predict

Examples
set.seed(120)
x <- matrix(rnorm(1000*20),ncol=20)
y <- sample(c(1:4),size=20,replace=TRUE)
mydata <- list(x=x,y=y)
mytrain <- pamr.train(mydata)
