Method fit()

Run the optimization for the model.

Usage

OptimGLM$fit(
  data_model,
  theta,
  ll,
  gr,
  hidden,
  pi_vector,
  npar,
  latent,
  family
)

Arguments

data_model

(DataModel())
The DataModel object contains data used in the fmmr6.

theta

(numeric())
The coefficients to estimates.

ll

(function())
The loglikelihood function.

gr

(function())
The gradient function.

hidden

(matrix())
The matrix of the posterior probability.

pi_vector

(numeric())
A vector of the prior probability pi.

npar

(integer())
Number of the parameters.

latent

(integer(1))
The number of latent classes

family

(character(1)|character())
The distribution family which can be either a string like "gaussian" or a vector like c("gaussian", "gaussian").

Returns

Return the optimization result with the estimates, the Loglikelihood value and the information criteria.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

OptimGLM$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
