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...

Computing all critical points of a monomial on very affine variety is fundamental task in algebraic statistics, particle physics and other fields. The number known as the maximum likelihood (ML) degree. When smooth, it coincides with Euler characteristic. We introduce degeneration techniques that are inspired by soft limits CEGM theory, we answer several questions raised literature. These perta...

The phenomenon of separation or monotone likelihood is observed in the fitting process of a logistic model if the likelihood converges while at least one parameter estimate diverges to +/- infinity. Separation primarily occurs in small samples with several unbalanced and highly predictive risk factors. A procedure by Firth originally developed to reduce the bias of maximum likelihood estimates ...
