An improvement on the maximum likelihood reconstruction of pedigrees from marker data

Many methods have been proposed to reconstruct the pedigree of a sample of individuals from their multilocus marker genotypes. These methods, like those in other fields of statistical inferences, may ...

Existence of Maximum Likelihood Estimates in Regression Models for Grouped and Ungrouped Data

This is a preview. Log in through your library . Abstract In general, concavity of the log likelihood alone does not imply that the MLE exists always. For a class of linear regression models for ...

Existence of Maximum Likelihood Estimates

The likelihood equation for a logistic regression model does not always have a finite solution. Sometimes there is a nonunique maximum on the boundary of the parameter space, at infinity. The ...
