For a given set of system parameters the objective function will be calculated based on defined cohorts and variance models.
calculate_objective(parameters, cfg, estimation = TRUE)
If estimation is TRUE
it will return the objective function
value, if it is FALSE
it will return a list with an element
value
containing the objective function value and an element named
isgood
that is TRUE if the objective function was successful.
system parameters
ubiquity system object
boolean variable to indicate if the objective function is being called during parameter estimation
