MCQ (Single Correct Answer)

-0.3

A regression model is used to express a variable $$Y$$ as a function of another variable $$X.$$ this implies that

There is a causal relationship between $$Y$$ and $$X$$

A value of $$X$$ may be used to estimate a value of $$Y$$

Values of $$X$$ exactly determine values of $$Y$$

There is no causal relationship between $$Y$$ and $$X$$
