Web30 Sep 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 ...
