Chapter 4 Describing the Relation between Two Variables
... 1. Is 0 a reasonable value for the explanatory variable? 2. Do any observations near x = 0 exist in the data set? A value of 0 is reasonable for the drilling data (this indicates that drilling begins at the surface of Earth. The smallest observation in the data set is x = 35 feet, which is reasonabl ...

Lecture 5 - Categorical and Survival Analyses
... • What’s interesting is that there are “lucky” and “unlucky” combinations of p (response rate) and N (sample size) • That is, for a given sample size: * for some p you may higher ability to make inference * for some p you may have less ability! • Not to scald the Wald, but not all CI’s are created e ...

Churn prediction in telecoms via data mining approach: A case
... Decision Tree approach is actually the predictive models that is most used in combination with others. Various algorithms can be used (CART, CHAID, C 5.0, etc), each of them have various parameters we can play with. That is why it is possible to build a lot of different models based on decision tree ...
