Multiple Choice

A) only if an omitted determinant of Yi is a continuous variable.
B) if an omitted variable is correlated with at least one of the regressors,even though it is not a determinant of the dependent variable.
C) only if the omitted variable is not normally distributed.
D) if an omitted determinant of Yi is correlated with at least one of the regressors.
