transformPvs
Description
Helper function to Transform PVs onto a new metric
(e.g., PISA Mean = 500, SD = 100).
Uses the method described in the PISA 2012 technical manual.
Usage
transformPvs(data, mT = 0, sdT = 1, weights = 1)
Arguments
data
A data frame or matrix that contains the PVs
mT
The desired mean of the PVs
sdT
The desired sd of the PVs
weights
a vector of weights, the same length as data[1] used to
calculate the mean and SD across the PVs
Value
a List of transformed PVs with as many elements as PVs were listed in 'x'.
