Q: Which inventory management technique classifies items based on importance?
Did You Know?
If we omit X, the error term in the misspecified model becomes (β₂X + u). The OLS estimator of the constant will be unbiased for β₁ only if X has zero mean in the sample, because then the omitted variable bias term vanishes. In general, omission causes bias.
