SPCModelNonparCenterScale {spcadjust} | R Documentation |
Nonparametric resampling of univariate observations. Updates are centered and scaled transformations of the data (with a constant potentially being subtracted).
SPCModelNonparCenterScale(Delta = 0)
Delta |
how much to subtract before scaling. |
Calls SPCModelNonpar
to generate the data object, so it only needs to specify the meaning of xi
, the parameter needed to compute updates and the definition of the updates.
xi: a list with two elements:
mu: the mean.
sd: the standard deviation.
updates(xi,data): returns the centered and scale version of the data from which Delta/2
has been subtracted, i.e.
\frac{data-mu-Delta/2}{sd}
An object of class SPCDataModel.
