Question

Fit five different models to  completion_time :  normal exponential gamma weibull lognormal  Which model has the lowest loglikelihood, and what does this mean?

Answer

Exponential, meaning the observed data are least likely under this model, so it fits the data worst of the five.

Answer

Gamma, meaning it fits the data worst, because it has the largest magnitude of error

Answer

Exponential, meaning it fits the data best, because a lower loglikelihood indicates less unexplained variation.

Answer

lognormal, meaning it fits the data best, because it is closest to zero among the negative values.

Answer

Normal, meaning it fits the data worst, because the normal distribution cannot model positive-only data.
