Importantly, the regression line in log-log space is straight (see above), but in the space defined by the original scales, it’s curved, as shown by the purple line below. Web5 feb. 2013 · Abstract This paper introduces a novel class of models for binary data, which we call log-mean linear models. They are specified by linear constraints on the log-mean linear parameter, defined as a log-linear expansion of the mean parameter of the multivariate Bernoulli distribution.
