logLik.drift_dm: Extract Log-Likelihood for a drift_dm Object

Description

This method extracts the log-likelihood for a drift_dm object if possible.

Usage

# S3 method for drift_dm
logLik(object, ...)

Value

A logLik object containing the log-likelihood value for the drift_dm object. This value has attributes for the number of observations (nobs) and the number of model parameters (df).

Returns NULL if the log-likelihood is not available (e.g., when the model has no observed data attached).

Arguments

object

a drift_dm object containing observed data

additional arguments

Examples

# get a pre-built model and a data set for demonstration purpose
# (when creating the model, set the discretization to reasonable values)
a_model <- dmc_dm()
obs_data(a_model) <- dmc_synth_data
logLik(a_model)
