Sample sizes and estimation methods for the Weibull distribution for unthinned slash pine plantation diameter distributions
1988
Three mehtods were evaluated over four sample sizes for prediction of diameter distributions in unthinned site prepared slash pine plantations. Maximum likelihood estimation provided the best estimates of known distribution parameters. Under the likely assumption that there are no specific underlying parameters, both modified moments estimation and a percentile estimator reproduce the underlying distribution of diameters as well or better than maximum likelihood estimation. All three methods require approximately 50 tree samples to reproduce distributions into classes with less than 10% error in any class. For. Sci. 34(3):809-814.
