## A function to estimate the taxon-wise NB-params

### Description

A function to estimate the taxon-wise NB-params

### Usage

    estNBparams(
      design,
      thetas,
      muMarg,
      psi,
      X,
      nleqslv.control,
      ncols,
      initParam,
      v,
      dynamic = FALSE,
      envRange,
      allowMissingness,
      naId
    )

### Arguments

`design` | an n-by-v design matrix
`thetas` | a vector of dispersion parameters of length p
`muMarg` | an offset matrix
`psi` | a scalar, the importance parameter
`X` | the data matrix
`nleqslv.control` | a list of control elements, passed on to nleqslv()
`ncols` | an integer, the number of columns of X
`initParam` | a v-by-p matrix of initial parameter estimates
`v` | an integer, the number of parameters per taxon
`dynamic` | a boolean, should response function be determined dynamically? See details
`envRange` | a vector of length 2, giving the range of observed environmental scores
`allowMissingness` | A boolean, are missing values present
`naId` | The numeric index of the missing values in X If dynamic is TRUE, quadratic response functions are fitted for every taxon. If the optimum falls outside of the observed range of environmental scores, a linear response function is fitted instead

### Value

a v-by-p matrix of parameters of the response function
