mnlHess {bayesm}

Computes –Expected Hessian for Multinomial Logit

Description

mnlHess computes expected Hessian (E[H]) for Multinomial Logit Model.

Usage

mnlHess(beta, y, X)

Arguments

beta

k x 1 vector of coefficients

y

n x 1 vector of choices, (1,\ldots,p)

X

n*p x k Design matrix

Details

See llmnl for information on structure of X array. Use createX to make X.

Value

k x k matrix

Warning

This routine is a utility routine that does not check the input arguments for proper dimensions and type.
