Estimate and validate a CUBE model for ordinal data, with covariates only for explaining the feeling component.
cubecsi(m, ordinal, W, starting, maxiter, toler)
An object of the class "CUBE". For cubecsi, $niter will return a NULL value since the optimization procedure
is not iterative but based on "optim" (method = "L-BFGS-B", option hessian=TRUE).
$varmat will return the inverse
of the numerically computed Hessian when it is positive definite, otherwise the procedure will return a matrix of NA
entries.
Number of ordinal categories
Vector of ordinal responses
Matrix of selected covariates for explaining the feeling component
Vector of initial parameters estimates to start the optimization algorithm, with length equal to NCOL(W) + 3 to account for an intercept term for the feeling component (first entry)
Maximum number of iterations allowed for running the optimization algorithm
Fixed error tolerance for final estimates
