Wait, you're telling me that MLR doesn't require the inputs to be independent? That's news to me! Option B must be the right answer then.

Yes, you're correct. MLR assumes that the X's are independent of each other.

Haha, this question is a piece of cake! Everyone knows that the inputs in MLR can't be correlated. Option A is clearly the correct answer.

Exactly, having correlated inputs can lead to multicollinearity issues in the regression analysis.

That's right, if the inputs are correlated, it violates one of the assumptions of MLR.

I agree, option A is the correct answer. The inputs in MLR should not be correlated.

Hmm, I thought MLR was all about the deliberate manipulation of the inputs to see their effect on the output. Option C seems like the answer to me.

User 2: Yeah, MLR is more about analyzing the relationship between inputs and output, not necessarily through deliberate experimentation.

I'm not sure about the answer, but I know that the residuals should be normally distributed for the model to be valid. Option D looks like the odd one out.

I agree, the residuals being normally distributed is a key aspect of MLR.

Option B seems like the correct answer here. The inputs in a valid MLR model should be independent of each other, not correlated.

But doesn't MLR assume that the residuals are Normally Distributed?
