The log-likelihood is just the (natural, usually) logarithm of the ordinary likelihood function. It is numerically easier to work with, and since log is a monotonic function, equivalent.<BR><BR ...

The log likelihood function can only be evaluated for , c > 0, and . In the estimation process, you must enforce these conditions using lower and upper boundary constraints. The three-parameter ...

The observed likelihood function of the three-parameter Weibull distribution is and the log likelihood, , is The log-likelihood function, , for is the objective function to be maximized to obtain the ...
