Chapter 12 Logistic Regression 12.1 Modeling Conditional Probabilities So far, we either looked at estimating the conditional expectations of continuous variables (as in regression), or at estimating distributions. There are many situations where however we are interested in input-output relationships, as in regression, but the output variable is discrete rather than continuous. In particular there
