The G statistic and its local version have been used extensively in spatial data analysis. The paper proves the asymptotic normality of the G statistic. Theorems in this paper imply the regular permutation test for the G statistic is valid.

A gene genealogy describes relationships among haplotypes sampled from a population. Knowledge of the gene genealogy for a set of haplotypes is useful for estimation of population genetic parameters and it also has potential application in finding disease-predisposing genetic variants. As the true gene genealogy is unknown, Markov chain Monte Carlo (MCMC) approaches have been used to sample gen...

This paper presents a method for detecting TCP SYN flooding attack using BENEF model. Our model relies on the significant parameters of anomalous network packets, the statistic of system behavior, and the decision with threshold and fuzzy rule-based technique. With fuzzy technique, rules or a set of rules corresponding with the appropriate membership value are designed for analysis and to find ...

Brushless DC (BLDC) motors are the most popular used by industry because they easy to control. BLDC generally controlled artificial controls such as Fuzzy Logic Controller (FLC), Artificial Neural Network (ANN), and Adaptive Neuro-Fuzzy Inference System (ANFIS). However, performance of control system in previous studies was compared separately with their respective parameters, making it difficu...

We consider the relative merits of various saddlepoint approximations for the c.d.f. of a statistic with a possibly non-normal limit distribution. In addition to the usual Lugannani-Rice approximation we also consider approximations based on higher-order expansions, including the case where the base distribution for the approximation is taken to be non-normal. This extends earlier work by Wood ...

In this paper we develop a new statistical test to determine whether quad or dual (including compact) polarisation modes are best for use in low frequency SAR applications. We first consider a general formulation of dual/compact modes and use it to expose a fundamental weakness in compact reconstruction algorithms. We then show how all dualpol scattering problems can effectively be localised ge...

Under the assumption of that the variance-covariance matrix is fully populated, Baarda’s w-test is turn out to be completely different from the standardized least-squares residual. Unfortunately, this is not generally recognized. In the limiting case of only one degree of freedom, all the three types of test statistics, including Gaussian normal test, Student’s t-test and Pope’s Tau-test, will ...

PROC SQL is SAS’ implementation of the ANSI Standard Query Language (SQL), an ANSI standard database programming/query language. Syntax is simple and its utility is broad in scope. As another capability, we find that PROC SQL is a very useful tool to perform exact test for monotonic trend in mean responses of discrete random variables. In this paper, we show utilization of PROC SQL to construct...

We consider the problem of testing the equality of J quantile curves from independent samples. A test statistic based on an L2-distance between non-crossing nonparametric estimates of the quantile curves from the individual samples is proposed. Asymptotic normality of this statistic is established under the null hypothesis, local and fixed alternatives, and the finite sample properties of a boo...
