与感知器类似的线性判别式是通过搜索可以最佳分隔各个类别的变量的线性组合来对训练集合中的所有点进行分类，最早的是Fisher线性判别式。

Results indicate that the ensemble precipitation probability forecasts made by the three methods above-mentioned all can give accurate estimation of center and region of the precipitation, and the "Rank" is superior to the "Average" and "Correlation" for performing better in forecasting the areas, intensity and boundary of precipitation but the other two expand improper areas.

结果表明：用上述3种方法制作的多模式短期集合概率预报都能对降水落区及中心做出较准确的预报，但平均法和相关法易使降水落区虚假放大，Rank法则能较好地刻画降水落区边界及强度，其概率预报效果优于平均法和相关法结果。
