# Should the log-likelihood value be reported?

Just a quick question. I have used maximum likelihood estimation to find the best-fit parameters of a model. In doing so I get a log likelihood value, which obviously is the highest log likelihood value of all parameter sets. However, when reporting these parameters in a paper, should the log likelihood value of that set be reported as well, or does that not have any significant value on its own?

• If you do report it, it's essential you provide a formula, because many algorithms and software packages do not actually compute the log likelihood: they compute a value that will differ from the true log likelihood by some (uncomputed) constant. – whuber Aug 16 '19 at 11:17

• It is also adequate to report a pseudo $R^2$ that is derived simply from the model likelihood ratio $\chi^2$ statistic (and for some indexes the maximum attainable log likelihood). – Frank Harrell Aug 16 '19 at 11:34
