I have some question about input vars in a proc logistics procedures:
1) I have a var that have int values from 10 to 30 (10,11,12...30). I don't if use it as 'quantitative' or 'classification'. I use 'quantitaive' for vars like sales (from 0 to 1000 and with decimals). Is there any criteria??
2) I have a qualitatitve var that have values 'A', 'D', 'T'. I can use as input var as 'classification'. But I have noticed that the target value changes a lot with the changes of values like this: A ( var target ascend), D (var target descend), T (var targer strongly ascend), I am thinking in use this mapping D ->1, A -> 2, T -> 3 and then I have a linear correlation between the target var and the input var. Can I use then this transformed var as a 'quantitaive' var. Does it make sense?
3) last question: can I get the cumulative lift chart or similar as output in proc logistics. I can see the 'ROC curve' but not lift chart
Any advice will be greatly appreciated
