An investigator observes that five independent risk factors influence the occurance of a disease. Which of the following statistical tests should be applied to assess the relationship between these 5 risk factors and the occurance of disease?
Correct Answer: Multiple Logistic Regression
Description: A multiple logistic regression model is used to study the effects of multiple predictor variables (e.g. risk factors and treatments) on categorical outcomes and the outcome is normally binary, such as the presence or absence of disease. Logistic models are regularly applied when studying the relationships between risk factors and the occurrence of disease in epidemiological studies. Ref: Topics in Biostatistics, By Walter T.
