KernelEquateFromDists: Apply Kernel Equating to Equivalent Groups.

In CambridgeAssessmentResearch/KernEqWPS: Kernel Equating Without Pre-Smoothing

Apply Kernel Equating to Equivalent Groups.

Description

Assumes that X and Y are taken by equivalent groups (or by the same group). Requires bandwidths for continuization to be supplied.

Usage

KernelEquateFromDists(scoresX, fX, scoresY, fY, hX, hY)

Arguments

scoresX	Vector of possible scores on form X.
fX	Number of people achieving each score on form X (weighted numbers, probabilities or proportions also acceptable). Must be same length as scoresX.
scoresY	Vector of possible scores on form Y.
fY	Number of people achieving each score on form Y (weighted numbers, probabilities or proportions also acceptable). Must be same length as scoresY.
hX	Bandwidth for form X.
hY	Bandwidth for form Y.

Value

The function returns a list with the following elements:

yxFunc

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 scoresX.
