"WebFor now, we take this expression as the simplest choice. The idea of maximum likelihood is to replace the ideal mean values with the theoretically “expected” values predicted by a linear-function model. The probability distribution then becomes a conditional probability. " - Chi-square and log-likelihood calculator

WebSep 30, 2016 · As I understand, logistic regression models can be compared by comparing the deviance. The deviance is defined by -2xlog-likelihood (-2LL). In most cases, the value of the log-likelihood will be negative, so multiplying by -2 will give a positive deviance. The deviance of a model can be obtained in two ways. First, you can use the value listed ...
