estNBparams {RCM}R Documentation

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)

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

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
