Suppose that the parameter vector is and that you want a confidence interval for .The profile likelihood function for is defined as where is the vector with the jth element fixed at and l is the log ...

Overdispersion occurs when the variance of Y exceeds the Var(y) above. That is, the variance of Y is , where >1. With overdispersion, methods based on quasi-likelihood can be used to estimate the ...

In this module we will learn what a likelihood function is and the concept of maximum likelihood estimation. We will construct maximum likelihood estimators (MLEs) for one and two parameter examples ...
