Normalize {QuantPsyc}

Normalize Data

Description

Convert data to Normal Scores with the same Mean and SD. This reshapes data to conform to a Normal Distribution. It is not converting to z-scores (i.e., it is not standardizing data)

Usage

Normalize(x) 

Arguments

x

Data to be normalized. Should be vector of scores

Value

A numeric with the same Mean and SD as x, but without skew or kurtosis

Warning

This is a primative function. I have a long to do list. For example, it is not yet written to handle missing observations.
