Hi,
I'm running a simulation in which a model will be fit to the simulated data 1000 times by running a loop.
However, some simulated data will make the model return error, like below:
Error: The job for model 'myModel' exited abnormally with the error message: Objective function returned a value of NaN at iteration 52.23.
May I use the option unsafe=TRUE in mxRun to skip error and continue the loop?
Thank you.
Best,
Jean

Hey Jean!
That should work. The unsafe argument to mxRun just omits the stop command when an error is encountered. Instead, the error is treated like a warning. It's probably a good idea to keep some kind of track of the models that fail. This can be done by saving and/or storing the output status.
yourModel@output$statusThis keeps the status code(s) and error/warning message(s). It is a list so you could probably turn it into a data.frame and keep records for all 1000 model runs.
data.frame(yourModel@output$status)Hey Mike, that's super helpful! Thank you~
