Hello, When we use optim and run into errors, such as generates NA/NaN/Inf, and the routine stops because of this error, is there a way to print the values of the argument of the functions where the error occurs? For example, I am doing minimizing negative log likelihood and when the optim stops because of those errors, I'd like to know what was the parameter values at that time. I heard nlm has something called "print.level" and I am wondering there is a way for optim as well. Thank you. Mikyoung Jun
You might want to try using options(error = recover) or perhaps options(error = browser). -roger Mikyoung Jun wrote:> Hello, > > When we use optim and run into errors, such as generates NA/NaN/Inf, and > the routine stops because of this error, is there a way to print the > values of the argument of the functions where the error occurs? > For example, I am doing minimizing negative log likelihood and when the > optim stops because of those errors, I'd like to know what was the > parameter values at that time.
