Mean log-likelihood

I use MAXLIK library to estimate multiple discrete-continuous extreme value (MDCEV) model.

After convergence, I got a mean log-likelihood value, -26.4448.

But I can find what it means. Is it different from a general log-likelihood value?

Please, answer this question.

The mean log-likelihood is being used to avoid precision problems because it can get very large sometimes, and it is best to keep numbers small on a computer.

To get the log-likelihood, multiply by the number of observations.
