Splits data, creates cluster and loads different pieces of the database on each worker.
apollo_makeCluster(
apollo_probabilities,
apollo_inputs,
silent = FALSE,
cleanMemory = FALSE
)
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", "shares_LL", or "raw".
List grouping most common inputs. Created by function apollo_validateInputs.
Boolean. If TRUE, no messages are printed to the terminal. FALSE by default. It overrides apollo_inputs$silent
.
Boolean. If TRUE, it saves apollo_inputs to disc, and removes database and draws from the apollo_inputs in .GlobalEnv and the parent environment.
Cluster (i.e. an object of class cluster from package parallel)
Internal use only. Called by apollo_estimate
before estimation. Using multiple cores greatly increases memory consumption.
