Abstract:

A heuristic approach to estimation using quantile functions is proposed and applied to constructing simple L-estimators of the parameters of Weibull and Pareto distributions. The general approach to construction involves starting with convenient "pivotal statistics" and refining them using the jackknife approach to obtain simple closed form estimators. Empirical studies of these L-estimators for Weibull and Pareto parameters so obtained show that they are essentially bias free and in terms of MSE compare very well with the MLE and other competitors.
