In normal theory exploratory factor analysis, likelihood ratio (LR) statistic plays an important role in evaluating the goodness-of-fit of the model. In this paper, we derive an approximation of the LR statistic. The approximation is then used to show explici…

This article is concerned with the problem of prediction for the future generalized order statistics from a mixture of two general components based on doubly type II censored sample. We consider the one sample prediction and two sample prediction techniques.…

Generalized linear mixed models (GLMMs) are typically constructed by incorporating random effects into the linear predictor. The random effects are usually assumed to be normally distributed with mean zero and variance-covariance identity matrix. In this pape…

This research tests for differences in mean class averages between male and female faculty for questions on a student rating of instruction form at one university in the Midwest are considered to be in the category of “very high research activity” by the Carn…

This paper considers the computation of sparse solutions of the linear complementarity problems LCP(<i>q</i>, <i>M</i>). Mathematically, the underlying model is NP-hard in general. Thus an <i>lp</i>(0 <<i> p </i>< 1) regularized minimization model is proposed…

We give a new way to price American options by using Samuelson’s formula. We first obtain the option price corresponding to a European option at time <i>t</i>, weighing it by the probability that the underlying asset takes the value <i>S</i> at time <i>t</i>.…

Extend Linear Expenditure System model is a collection of multiple linear models, and modeling is a clearly tedious process. The innovation of this paper is trying to find a simple way of ELES modeling, which means, in order to omit the modeling process one b…

For two-way contingency tables with ordered categories, the present paper gives a theorem that the independence model holds if and only if the logit uniform association model holds and equality of concordance and discordance for all pairs of adjacent rows and…

Zero-inflated negative binomial distribution is characterized in this paper through a linear differential equation satisfied by its probability generating function.

Group testing is a method of pooling a number of units together and performing a single test on the resulting group. It is an appealing option when few individual units are thought to be infected leading to reduced costs of testing as compared to individually…
