The Classical Linear Regression Model (CLRM) correct answers Assumptions: The model is linear in the parameters The explanatory variables X are uncorrelated with the error term The previous assumption leads to E(e|X)=0 The model is correctly specified (i.e. there is no specification bias). This means that we included all relevant variables There is no correlation between two error terms. i.e. cov(ui, uj)=0 u ~ N(0, s2). Homoskedasticity correct answers refers to the assumption that t...
