Description

Creates a dataset for CCRS from a preference data matrix.

Usage

create.ccrsdata(X,q=q)

Arguments

X

An n by m categorical data matrix.

q

An integer indicating the maximum rating.

Details

For the difference between Mmat.q and Mmat.q1 in the resulting list, see Section 3.2 in reference paper.

Value

Returns a list with the following elements.

Fmat

An n by q-1 matrix of scaled rank-ordered boundary data.

Mmat.q1

A q-1 by 3+1 matrix of I-spline basis functions, evaluated at the boundaries. +1 indicates all 0 intercepts.

Mmat.q

A q by 3+1 matrix of I-spline basis functions, evaluated at the midpoints between boundaries.
