SAS Statistical Business Analysis Using SAS 9: Regression and Modeling — Question 25

A researcher is planning a logistic regression to model the probability of disease occurrence. The researcher determines the rate of disease occurrence in the population is 1%.
For which of the following would this study be a candidate?

Answer options

• A. over fitting
• B. oversampling
• C. multicollinearity
• D. simple random sample

Correct answer: C

Explanation

The correct answer is C, multicollinearity, which can occur when predictor variables in the model are highly correlated, potentially skewing the results. Options A and B are not directly related to the concerns of modeling with such a low incidence rate, and D refers to a sampling method that does not address the underlying correlation issues among variables.
