A method of detection of outliers from the exponential distribution is given by sample fractile to construct test statistics.

利用样本分位数构造检验统计量，给出来自于指数分布总体异常数据的一种检测方法。

Post stack seismic attributes such as seismic energy fractile frenquecy, dipping angle variance, instantaneous dipping angleetc. can be used to predict fracture developing band.

利用地震能量分位数频率、倾角方差和瞬时倾角等叠后地震属性可对裂缝发育带进行定性预测。
