When you run a regression analysis, the variance of the error terms must be constant, so we can assume that the variance in the error terms is constant.

A1: There is a linear relationship between X and Y. A2: The error terms (and thus the Y's at each X) have constant variance. A3: The error terms are independent.

The four assumptions are: Linearity of residuals. Independence of residuals. Normal distribution of residuals. Equal variance of residuals. Linearity – we draw a.

I always think about the error term in a linear regression model as a random variable, with some distribution and a variance. So if the error terms come from this.
