### Maximum Likelihood Estimation

Maximum Likelihood Estimation The likelihood and log-likelihood functions are the basis for deriving estimators for parameters, given data. While the shapes of these two functions are different, they have their maximum point at the same value.

### The Likelihood, the prior and Bayes Theorem

Likelihood L (Y, ) or[Y|] the conditional density of the data given the parameters. Assume that you know the parameters exactly, what is the distribution of the data?
