Webb5 juni 2012 · In this chapter we want to discuss several diagnostic measures available that allow us to detect outliers and observations with high influence. Many of these have a parallel measure in linear regression, discussed in Chapter 5. There are options in proc logistic to print and plot these. Before we get to that, let's introduce another example. WebbLogistic regression is a parametric model, in which the model is defined by having parameters multiplied by independent variables to predict the dependent variable. Decision Trees are a non-parametric model, in which no pre-assumed parameter exists. Implicitly performs variable screening or feature selection. chris curran author
