This function updates the latent utility vector in the ranked probit case.
update_U_ranked(U, sys, Sigmainv)
U |
The current utility vector of length |
sys |
A vector of length |
Sigmainv |
The inverted error term covariance matrix of dimension
|
This update is basically the same as in the non-ranked case, despite that the truncation point is zero.
An updated utility vector of length J-1
