Further, we show how to extend these methods to adjust for known risk factors, and evaluate some important estimation difficulties that arise when relatively few data are available.
The DVT data is used to illustrate the methods and to identify some important differences. For example, consider where a single risk factor is of interest, then the logistic regression model is: (Model. 1 ) with unknown parameters (intercept) and (slope representing the association between factor and binary outcome ).
The logit outcome probability for subject, is then a linear function of the factor.
