This is the log odds of success to failure for the hth subpopulation. A nice property of the logistic model is that all possible values of in map into (0,1) for . Note that are the odds ratios.

In recent columns we showed how linear regression can be used to predict a continuous dependent variable given other independent variables 1,2. When the dependent variable is categorical, a common ...
