cgetC: Obtain A List of Cut-offs for Scale Usage Problems
Description
cgetC obtains a list of censoring points, or cut-offs, used
in the ordinal multivariate probit model of Rossi et al (2001).
This approach uses a quadratic parameterization of the cut-offs.
The model is useful for modeling correlated ordinal data on a
scale from 1, ..., k with different scale usage patterns.
Usage
cgetC(e, k)
Arguments
e
quadratic parameter (>0 and less than 1)
k
items are on a scale from 1, ..., k
Value
A vector of k+1 cut-offs.
Warning
This is a utility function which implements no error-checking.
