Resolved: log-likelihood

since the log-likelihood is always negative and numerically speaking the bigger a negative number the smaller it it. so when you say it should be big >> are we talking about the absolute value or not >> is it better to get -23 or -400

Hi Doaa!

Thanks for reaching out!

When comparing log-likelihood values, we don't consider the absolute values. Instead, we look at the raw values themselves.

A log-likelihood value that is closer to zero (less negative) indicates a better fit.Therefore, a log-likelihood of -23 is better than a log-likelihood of -400 because -23 is closer to zero. 

So, when we say the log-likelihood should be big, we are referring to the raw value being closer to zero, not the absolute value.

Hope this helps.

Best,

Ivan
