Comparison of Parameter Estimation Methods for the Three-Parameter Generalized Pareto Distribution
three-parameter generalized Pareto distribution moments probability-weighted moments maximum likelihood principle of maximum entropy least squares
2009/1/12
The generalized Pareto distribution, which is a special case of both exponential and Wakeby distribution, has good potential for the analysis of flood peaks because of its inherent properties. In this...
Effects of pre-freezing treatment methods on the quality retentionof thawed areca fruit
areca fruit quick freezing protection color microwave liquid nitrogen
2008/11/26
The effects of different treatments, before freezing, on thawed areca fruit were studied in this paper. Blanching in 0.5% sodium bicarbonate solution or water had no effect on the prevention of color ...
