This paper examines the channel holding time of public cellular telephony systems. This is the time that the Mobile Station (MS) remains in the same cell, a fraction of the call holding time. The study is based on actual data taken from a working system. The probability distribution that fits the empirical sample best when applying the Kolmogorov-Smirnov test is a mixture of lognormals. Combina...

In this study I briefly illustrate application of the Gaussian mixtures to approximate empirical distributions of financial indices (DAX, Dow Jones, Nikkei, RTSI, S&P 500). The resulting distributions illustrate very high quality of approximation as evaluated by Kolmogorov-Smirnov test. This implies further study of application of the Gaussian mixtures to approximate empirical distributions of ...

By using the brute force algorithm, the application of the two-dimensional two-sample Kolmogorov–Smirnov test can be prohibitively computationally expensive. Thus a fast algorithm for computing the two-sample Kolmogorov–Smirnov test statistic is proposed to alleviate this problem. The newly proposed algorithm is O(n) times more efficient than the brute force algorithm, where n is the sum of the...

Objective: To analyze retrospectively the surgical outcomes of a group of patients with bone metastases and multiple myeloma in the spine, which underwent neurological decompression and arthrodesis using pedicle screws, by isolated posterior approach, to check whether the operated patients present clinical improvement regarding the pain and neurological deficit compared to the preoperative peri...

This paper introduces a Kolmogorov-type test for the shortfall order (also known in the literature as the right-spread or excess-wealth order) against parametric alternatives. In the case of the null hypothesis corresponding to the Negative Exponential distribution, this provides a test for the new better than used in expectation (NBUE) and for the new worse than used in expectation (NWUE) prop...

A theme of recent side-channel research has been the quest for distinguishers which remain e ective even when few assumptions can be made about the underlying distribution of the measured leakage traces. The Kolmogorov-Smirnov (KS) test is a well known nonparametric method for distinguishing between distributions, and, as such, a perfect candidate and an interesting competitor to the (already m...

June 4, 2010 Xiaofeng Shao and Xianyang Zhang University of Illinois at Urbana-Champaign Abstract: This article considers the CUSUM-based (cumulative sum) test for a change point in a time series. In the case of testing for a mean shift, the traditional KolmogorovSmirnov test statistic involves a consistent long run variance estimator, which is needed to make the limiting null distribution free...
