Repeat problem 3 using cancer part of the present problem (CAN) as the factor of interest and type of admission (TYP) as a potential adjustment and interaction variable.

In the ICU data vital status at discharge (STA) is the outcome variable and consider history of chronic renal failure (CRN) as the factor of interest. Using logistic regression, demonstrate and then explain why age (AGE) is needed to adjust the effect of CRN. Using logistic regression modelling, demonstrate that there is no statistical interaction between age (AGE) and history of chronic renal failure (CRN).
