Assumptions of OLS 
Linearity Assumption: E[Y] = β0 + β1x. We are assuming the expected value of Y for any given X is a linear function of X (approximates to a straight line) 2. 
Assumption about errors: We assume the error terms are independently and identically distributed (iid) normal random variables with 0 mean and variance σ. 3. 
Assumptions about predictors: For multiple regression (more than 1 predictor) we assume the predictors are linearly independent. Heteroskedasticity might requi...
