NBjacobianPsi: Jacobian for the psi of a given dimension

In RCM: Fit row-column association models with the negative binomial distribution for the microbiome

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	the n-by-p count matrix
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
