Provides a wrapper for the bootstrap function tilt.boot
from the
boot
R package.
Implements nonparametric tilted bootstrap for PLS
regression models by case resampling : the tilt.boot
function will
run an initial bootstrap with equal resampling probabilities (if required)
and will use the output of the initial run to find resampling probabilities
which put the value of the statistic at required values. It then runs an
importance resampling bootstrap using the calculated probabilities as the
resampling distribution.

object 
An object of class 
typeboot 
The type of bootstrap. Either (Y,X) boostrap
( 
statistic 
A function which when applied to data returns a vector
containing the statistic(s) of interest. 
R 
The number of bootstrap replicates. Usually this will be a single
positive integer. For importance resampling, some resamples may use one set
of weights and others use a different set of weights. In this case 
alpha 
The alpha level to which tilting is required. This parameter is
ignored if 
sim 
A character string indicating the type of simulation required.
Possible values are 
stype 
A character string indicating what the second argument of

index 
The index of the statistic of interest in the output from

stabvalue 
Upper bound for the absolute value of the coefficients. 
... 
ny further arguments can be passed to 
An object of class "boot".
