Re: Applied Analytics Using SAS Enterprise Miner
I would be grateful if someone could explain the meaning of the following sections in the Output window of a Modelling node (below are screenshots from the Decision Tree based on page 3-84 of the course notes):
1. Classification Table: how are percentages under "Target Percentage" and "Outcome Percentage" calculated?

2. Assessment Score Distribution: are counts under "Number of Events" and "Number of Nonevents" based on the actual values in the Target variable or the predicted classification values/categories?

3. When defining prior probabilities, the values under "Number of Events" and "Number of Nonevents" contain decimal places, as if the observations had been split into fractions (below is a screenshot from the output of the Regression node based on example at page 6.30):
