apollo_makeLogLike

Creates log-likelihood function.

Description

Creates log-likelihood function from the likelihood function apollo_probabilities provided by the user.

Usage

apollo_makeLogLike(
  apollo_beta,
  apollo_fixed,
  apollo_probabilities,
  apollo_inputs,
  apollo_estSet,
  cleanMemory = FALSE
)

Arguments

apollo_beta

Named numeric vector. Names and values for parameters.
apollo_fixed

Character vector. Names (as defined in apollo_beta) of parameters whose value should not change during estimation.
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 "estimate" (default), "prediction", "validate", "conditionals", "zero_LL", or "raw".

apollo_inputs

List grouping most common inputs. Created by function apollo_validateInputs.
apollo_estSet

List of estimation options. It must contain at least one element called estimationRoutine defining the estimation algorithm. See apollo_estimate.
cleanMemory

Logical. If TRUE, then apollo_inputs$draws and apollo_inputs$database are erased throughout the calling stack. Used to reduce memory usage in case of multithreading and a large database or number o draws.

Details

Internal use only. Called by apollo_estimate before estimation. The returned function can be single-threaded or multi-threaded based on the model options.

Value

apollo_logLike function.
