T2 {mvdalab} | R Documentation |
Generates a Hotelling's T2 Graph
Description
Generates a Hotelling's T2 Graph both mvdareg
and mvdapca
objects.
Usage
T2(object, ncomp = object$ncomp, phase = 1, conf = c(.95, .99), verbose = FALSE)
Arguments
object |
an object of class |
ncomp |
the number of components to include in the calculation of Hotelling's T2. |
phase |
designates whether the confidence limits should reflect the current data frame, |
conf |
the confidence level(s) to use for upper control limit. |
verbose |
output results as a data frame |
Details
T2
is used to generates a Hotelling's T2 graph both PLS and PCA models.
Value
The output of T2
is a graph of Hotelling's T2 and a data frame listing the T2 values.
