I feel like B is also a good choice. The sum of residuals being zero is a common property.

I agree, C makes sense. It’s too strict for regression.

I think the answer is C. Not all standardized residuals need to be within 3 SD.

I thought it was normal for some to be outside 2 SDs.

B is a must for valid regression, right?

Wait, are all standardized residuals really supposed to be within 3 SDs?

I’m a bit confused about the normal distribution part. I thought the residuals should follow a normal distribution, but I guess it could be an exception in some cases?

I feel like most standardized residuals being within 2 standard deviations is a common characteristic, so I’m leaning towards A or C as the answer.

I remember practicing a question about residuals, and I think the sum of residuals being zero is a key property of regression. So maybe it's not B?

I think the answer might be C, but I'm not entirely sure if all standardized residuals have to be within 3 standard deviations.
