A perfect fitting model would have a likelihood equal to 1 and -2LL equal to 0.

Question

Quizplus · Accepted Answer

A perfect fitting model would have a likelihood of 1, indicating that the model perfectly predicts the observed data. Since -2 times the log likelihood (-2LL) is used to measure model fit, with lower values indicating better fit, a likelihood of 1 would result in a log likelihood of 0, and thus -2LL would also equal 0, indicating perfect fit.
