Ascertainment bias can make estimation ... of maximum likelihood conditioned on the mating type of the parents. Testing of specific hypotheses is also possible by a likelihood ratio test.

We begin with estimating relationship. Table 2 A list of all possible pairs ... relationships could be used for comparison. Likelihood ratios were used to evaluate the relative degree of support ...

Then, maximum likelihood estimation is performed under the constraint ... When a Type 3 analysis is requested, PROC GENMOD produces a table that contains the likelihood ratio statistics, degrees of ...

Note that this is not in general a likelihood-based method of estimation, so that inferences based on likelihoods ... models the association between pairs of responses with log odds ratios, instead of ...
