the technical efficiency involved in cocoa production in cross river state was estimated using the stochastic frontier production function analysis. the effects of some selected socio- economic characteristics of the farmers on the efficiency indices were also estimated. the study relied upon primary data generated from interviewing cocoa farmers using a set of structured questionnaire. a multi...

Summary The classical likelihood ratio test based on the asymptotic chi-squared distribution of log-likelihood is one fundamental tools statistical inference. A recent universal approach sample splitting provides valid hypothesis tests and confidence sets in any setting for which we can compute split statistic, or, more generally, an upper bound null maximum likelihood. finite samples without r...

The method of maximum likelihood (ML), introduced by Fisher (1921), is widely used in human and quantitative genetics and we draw upon this approach throughout the book, especially in Chapters 13–16 (mixture distributions) and 26–27 (variance component estimation). Weir (1996) gives a useful introduction with genetic applications, while Kendall and Stuart (1979) and Edwards (1992) provide more ...
