update_d function

Update utility threshold increments

This function updates the utility threshold increments

update_d(d, y, mu, ll, zeta, Z, Tvec)

Arguments

• d: The current vector of utility threshold increments.
• y: A matrix of the choices.
• mu: A matrix of the systematic utilities.
• ll: Current log-likelihood value.
• zeta: The mean vector of the normal prior for d.
• Z: The covariance matrix of the normal prior for d.
• Tvec: The element Tvec in sufficient_statistics.

Returns

The updated value for d.
