apollo_llCalc: Calculates log-likelihood of all model components

In apollo: Tools for Choice Model Estimation and Application

Calculates log-likelihood of all model components

Description

Calculates the log-likelihood of each model component as well as the whole model.

Usage

apollo_llCalc(apollo_beta, apollo_probabilities, apollo_inputs, silent = FALSE)

Arguments

apollo_beta	Named numeric vector. Names and values for parameters.
apollo_probabilities	Function. Returns probabilities of the model to be estimated. Must receive three arguments: apollo_beta: Named numeric vector. Names and values of model parameters. apollo_inputs: List containing options of the model. See apollo_validateInputs. functionality: Character. Can be either "components", "conditionals", "estimate" (default), "gradient", "output", "prediction", "preprocess", "raw", "report", "shares_LL", "validate" or "zero_LL".
apollo_inputs	List grouping most common inputs. Created by function apollo_validateInputs.
silent	Boolean. If TRUE, no information is printed to the console by the function. Default is FALSE.

Details

This function calls apollo_probabilities with functionality="output". It then reorders the list of likelihoods so that "model" goes first.

Value

A list of vectors. Each vector corresponds to the log-likelihood of the whole model (first element) or a model component.
