| Abstract: | Four methods of estimating the three-parameter Weibull distribution were evaluated by computer simulation and field data comparison. Through computer simulation, regression Estimator is the best method. However, The simulation result of Chinese fir plot data is not so good. Other three methods, maximum likelihood estimator, moments estimator and percentile estimator almost give the same results as estimate parameter b and c of Weibull distribution by the field data. Considering that computer calculation will take a lot of time, the percentile estimator is the best one. |
