LinearEquate: Apply linear equating to data from a EG design.

In CambridgeAssessmentResearch/KernEqWPS: Kernel Equating Without Pre-Smoothing

Apply linear equating to data from a EG design.

Description

Apply linear equating to data from a EG design.

Usage

LinearEquate(xscores, yscores)

Arguments

xscores	A vector of scores from individual candidates on form X.
yscores	A vector of scores from individual candidates on form Y.

Value

The function returns a list with the following elements:

lys

A function that translates any vector of scores on form X into equivalent scores on form Y.

yx

A vector representing the scores derived from applying yxFunc to a sorted list of all the unqiue form X scores that actually occur in the data.

Examples

#Simulate two vectors with differencein means of 10
x=rnorm(500,50,10)
y=rnorm(500,60,10)
lineq=LinearEquate(x,y)
lineq$lys(45:50)
