About this document
OLS Assumptions and Parameter Estimates by shaziadurrani is a document available to read on EtoBox.
1. Biased slope estimates can occur due to measurement error, misspecification, omitted variables, or inclusion of irrelevant variables. 2. Centering variables subtracts the mean from each value, changing the intercept but not the slope or other estimates. 3. Heteroskedasticity, where the variance of the error term is not constant, violates OLS assumptions and can inflate or deflate standard errors.
