Jacobian for the psi of a given dimension

Description

Jacobian for the psi of a given dimension

Usage

NBjacobianPsi(beta, X, reg, muMarg, theta, preFabMat, allowMissingness, naId)

Arguments

beta

a scalar, the current estimate

X

reg

the regressor matrix, the outer product of current row and column scores

muMarg

the nxp offset matrix

theta

a n-by-p matrix with the dispersion parameters

preFabMat

a prefab matrix, (1+X/thetas)

allowMissingness

A boolean, are missing values present

naId

The numeric index of the missing values in X

Value

The evaluation of the jacobian function at beta, a 1-by-1 matrix
