Sale price: $5.00


This paper compares seven approximately unbiased ratio estimators along side with the classical ratio estimator under a non-normal linear regression model. The variances, bias, mean squared errors and efficiencies of these estimators for the ratio of population means of two characters were compared using Monte Carlo. Our findings revealed that  A    estimator is the best.
