... Likelihood function is the joint pmf or pdf of X which is the function of unknown values when x's are observed. The maximum likelihood estimates are the values which maximize the likelihood function. Steps to follow: (i) Determine the likelihood function. (ii) Take the natural logarithm of the l ...
