# Thread: Maximum Likelihood Estimate For A Poisson Mass Function ...

1. ## Maximum Likelihood Estimate For A Poisson Mass Function ...

with mean μ is ((μ ^ x) * ((exp) ^ -μ)) / x!

The log likelihood is x * log(μ) − μ. (Answer)

How do I arrive at the log likelihood provided?

Can I get a refresher on logs please?

Hey dorkboy.

The log laws are such that log(xy) = log(x) + log(y) and log(a/b) = log(a) - log(b), and log(a^b) = b*log(a).

Thanks for the great summary chiro.
