  restrictions = NULL,
  restrictions.phi = NULL
)

Arguments

mod

an object of class bbdml

mod_null

Optional. An object of class bbdml. Defaults to NULL

restrictions

Optional. Defaults to NULL. Numeric vector indicating the parameters associated with the abundance to test, or character vector with name of variable to test. Note that 1 is the intercept associated with the abundance.

restrictions.phi

Optional. Defaults to NULL. Numeric vector indicating the parameters associated with the dispersion to test, or character vector with name of variable to test. Note that 1 is the intercept associated with the dispersion.

Value

A list with mu representing the index of the restricted covariates associated with abundance and phi representing the index of the restricted covarates associated with the dispersion
