## The score function of the response function for 1 taxon at the time

### Description

The score function of the response function for 1 taxon at the time

### Usage

    dNBllcol_constr(betas, X, reg, theta, muMarg, psi)

### Arguments

`betas` | a vector of v parameters of the response function of a single taxon
`X` | the count vector of length n
`reg` | a n-by-v matrix of regressors
`theta` | The dispersion parameter of this taxon
`muMarg` | offset of length n
`psi` | a scalar, the importance parameter Even though this approach does not imply normalization over the parameters of all taxa, it is very fast and they can be normalized afterwards

### Value

A vector of length v with the evaluation of the score functions
