Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Kolmogorov-Smirnov type testing for structural breaks: A new adjusted-range based self-normalization approach
结构断裂 Kolmogorov-Smirnov检验 KS检验 调整范围 自归一化方法
2023/4/23
A popular self-normalization (SN) approach in time series analysis uses the variance of a partial sum as a self-normalizer. This is known to be sensitive to irregularities such as persistent autocorre...

2017/3/22
In this paper we present three methods for evaluating range rates of meteoroids
passing through the ionosphere, using linear frequency modulated (LFM) chirped pulse
data from the ALTAIR radar. The f...
