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

time_max
Seconds used for optimisiation. -
time_draw
Seconds used by functionTMB::sdreport()
. -
iter
Number of iterations required for optimization. -
message
Message about convergence returned by optimizer.
