computations: Information on Computations Performed Duration Model Fitting

Description

Get information on computations performed by function fit(). The information includes the total time used for fitting, and the time used for two particular tasks that can be slow: running the optimizer stats::nlminb(), and drawing from the multivariate normal returned by the TMB. It also includes values returned by the optimizer: the number of iterations needed, and messages about convergence.

Usage

computations(object)

Value

A tibble with the following variables:

• time_total Seconds used for whole fitting process.

• time_optim Seconds used for optimisiation.

• time_report Seconds used by function TMB::sdreport().

• iter Number of iterations required for optimization.

• message Message about convergence returned by optimizer.

Arguments

object

A fitted object of class "bage_mod".

                data = nzl_divorces,
                exposure = population) |>
