cumulative percentage distribution的意思|示意

Prediction rate is the cumulative distribution function of the area percentage of the landslides not used to construct a model with respect to the classes in the prediction map generated.

滑坡预测模型的预测率是，模型预测结果图的各个级别类型中，未用于建模的滑坡面积百分比的累积分布函数。

So it is obvious that the earthquakes do not always occur in the high cumulative percentage area but normally occur in the areas in which the distribution of the cumulative percentage is distinct.

由此可见，地震不一定发生在形变累积率高的地区，而通常发生在多年形变累积率空间分布差异性显著的地区。
