A likelihood function for the frequency of the A1 allele when 2 A1 alleles are observed in a sample of 10 alleles. The vertical dashed line is drawn through the maximum value of the likelihood ...

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 ...
