How Are Coefficient Estimates from WLS (Weighted Least Squares)interpreted

question 9

Multiple Choice

How are coefficient estimates from WLS (weighted least squares) interpreted?

• A)they must be scaled up by the weight used in order to calculate marginal effects
• B)there is no difference in interpretation since each observation is scaled by the same divisor
• C)take the inverse of the natural logarithm of the coefficient to find marginal effects
• D)They should only be used for hypothesis testing.Coefficient estimates from the un-weighted,original model should be used for prediction.
