Since the estimator of parameters are biased then Mean Square Error for comparing these two estimators was used. Simulation has been conducted using several sample sizes and different parameters. Our study support Razali’s result that the method of moments is more efficient than that least square methodotherWeibull DistributionMoments methodLeast Square methodOther
