Balakrishnan skew logistic distribution

Abstract

Based on Balakrishnan's (2002 Balakrishnan, N. (2002). Discussion on “Skew multivariate models related to hidden truncation and/or selective reporting” by B.C. Arnold and R.J. Beaver. Test 11: 37–39.[Web of Science ®] , [Google Scholar]) novel idea, a new skew logistic distribution is proposed. It contains Azzalini's skew logistic and standard logistic distributions as particular cases. Several mathematical properties of the proposed distribution (including characteristic function, cumulative distribution function, stochastic orderings, and simulation schemes) are derived. A real-data application is used to illustrate practical usefulness.     

Phase I Analysis of Multiple Linear Regression Profiles

This article considers the Phase I analysis of data when the quality of a process or product is characterized by a multiple linear regression model. This is usually referred to as the analysis of linear profiles in the statistical quality control literature. The literature includes several approaches for the analysis of simple linear regression profiles. Little work, however, has been done in the analysis of multiple linear regression profiles. This article proposes a new approach for the analysis of Phase I multiple linear regression profiles. Using this approach, regardless of the number of explanatory variables used to describe it, the profile response is monitored using only three parameters, an intercept, a slope, and a variance. Using simulation, the performance of the proposed method is compared to that of the existing methods for monitoring multiple linear profiles data in terms of the probability of a signal. The advantage of the proposed method over the existing methods is greatly improved detection of changes in the process parameters of linear profiles with high-dimensional space. The article also proposes useful diagnostic aids based on F-statistics to help in identifying the source of profile variation and the locations of out-of-control samples. Finally, the use of multiple linear profile methods is illustrated by a data set from a calibration application at National Aeronautics and Space Administration (NASA) Langley Research Center.     

Lie detection across cultures

Can people detect deception by watching a liar's nonverbal behavior? Can lies be detected across cultures? In the current paper, we report the first cross-cultural study to date of the detection of deception from nonverbal behavior. Americans and Jordanians were videotaped while telling lies and truths; other Americans and Jordanians watched the resulting videotapes and made lie detection judgments. Results showed similar patterns of lie detection within each of the two culture but no lie detection across cultures. In both the U.S. and Jordan, people who avoided eye contact and paused in the middle of speaking were judged to be deceptive. The findings are discussed within an adaptive perspective.     

On the consistency of choice

Consistency of choice is a fundamental and recurring theme in decision theory, social choice theory, behavioral economics, and psychological sciences. The purpose of this paper is to study the consistency of choice independent of the particular decision model at hand. Consistency is viewed as an inherently logical concept that is fundamentally void of connotation and is thus disentangled from traditional rationality or consistency conditions imposed on decision models. The proposed formalization of consistency takes two forms: internal consistency, which refers to the property that a choice model does not generate contradictory statements; and semantic consistency, which refers to the idea that a theory’s predictions are valid with respect to some observed data. In addressing semantic consistency, the relationship between theory and data is analyzed in terms of so-called duality mappings, which allow a passage between the two universes in a way that consistency is preserved. The formalization of consistency concepts relies on adapting the revealed preference theory to the context-dependent setting. The paper concludes by discussing the implications of the proposed framework and how it relates to classical revealed preference theory and other formalizations of the relationship between the theory and reality of choice.

A Monte Carlo study of REML and robust rank-based analyses for the random intercept mixed model

Restricted maximum likelihood (REML) methods are traditionally used for analyzing mixed models. Based on a multivariate normal likelihood, these analyses are sensitive to outliers. Recently developed robust rank-based procedures offer a complete analysis of mixed model: estimation of fixed effects, standard errors, and estimation of variance components. The results of a large Monte Carlo study are presented, comparing these two analyses for many situations over multivariate normal and contaminated normal distributions. The rank-based analyses are much more powerful and efficient than the REML analyses over all non-normal situations, while losing little power for normal errors.     

Application of multivariate longitudinal models in SIRT6, FBS,and BMI analysis of the elderly

Abstract

Objective: SIRT6 is a main regulator of metabolism and lifespan and its importance has been implicated in the prevention against aging-related diseases. The objective of this study was to examine the application of multivariate longitudinal models in SIRT6, FBS, and BMI analysis in the elderly men after eight weeks concurrent training with supplementation of l-arginine (l-Arg).

Methods: Thirty two elderly men with mean age of 63.09?±?3.71 years were randomly divided into four equal-sized groups (each n?=?8); Exercise?+?supplement (ES) group; exercise?+?placebo (EP) group; supplement (S) group and control (C) group. The ES and EP groups performed the eight weeks of concurrent training, three sessions per week. Group ES and group S consumed 1000?mg of l-Arg per day at 8:00?pm. Measurements of biochemical variables were done by ELISA Reader method. For analytical purposes, we used the paired sample t-test and multivariate longitudinal modeling with generalized estimating equation (GEE) methodology. All analyses have been implemented in R-3.4.1. p Values less than .05 were considered statistically significant.

Results: With respect to significant association between sirt6, FBS, and BMI, this study showed that synergy effect of training and supplementation was greater than the sum of their individual effects on SIRT6 (β?=?0.79, p?<?.001), FBS (β?=??5.56, p?=?.022), and BMI (β?=??3.89; p?=?.041). Also exercise alone had a significantly larger effect than supplementation alone on responses.

Conclusions: It can be concluded that the joint usage of concurrent training and supplement of l-Arg for elderly men could improve the metabolism and body composition.     

Collective identity and readiness for social relations with Jews among Palestinian Arab students at the David Yellin Teacher Training College in Israel

This paper argues that the two national components of identity among Palestinian Arab students in Israel—the Arab component and the Palestinian component—are strong, while the civil Israeli component is very weak. This paper also argues that although social relations between Arab students and Jewish students are very limited, the readiness of Arab students for professional and social relations with Jewish students is greater than the perceived readiness of Jewish students for social relations with Arab students. Correlation coefficients between collective identity and readiness for social relations with Jews reveal that there is no connection between the components of collective identity of Arab students and their familiarity with Jewish students and readiness to have professional and social relations with them.     

塔哈·侯赛因的《山鲁佐德之梦》与鲁迅的《补天》对比研究

塔哈·侯赛因的《山鲁佐德之梦》与鲁迅的《故事新编》均重视从多个层面对神话人物进行塑造,并在其中凝聚作者的哲学、政治、思想以及对社会的关注,使神话形象言其所不能。这两部作品在形式上存在诸多相似点,而在主题和内容方面却大相径庭。利用神话人物反映现实生活的手法,在鲁迅和塔哈·侯赛因的笔下得到完美的体现,这正是源于两位作家杰出的创造力和想象力。
