Multivariate regression tree methodology is developed and illustrated in a study predicting the abundance of several cooccurring plant species in Missouri Ozark forests. The technique is a variation of the approach of Segal (1992) for longitudinal data. It has the potential to be applied to many different types of problems in which analysts want to predict the simultaneous cooccurrence of sever...

Multivariate statistical analysis is an important data analysis technique that has found applications in various areas. In this paper, we study some multivariate statistical analysis methods in Secure 2-party Computation (S2C) framework illustrated by the following scenario: two parties, each having a secret data set, want to conduct the statistical analysis on their joint data, but neither par...

Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer-related death in the world. A 2005 analysis of the global incidence and cancer-related mortality revealed that 934,000 new cases of GC were diagnosed and approximately 700,000 patients died from this disease in 2002 (Parkin et al., 2005). Approximately 60% of all cases occur in developing countries with ...

background: few investigations have focused on the patients with lupus nephritis (ln) and neuropsychiatric systemic lupus erythematosus (npsle). this study was aimed to investigate the clinical features, mortality, and the predictors for mortality of this group of patients. patients and methods: medical records were retrospectively reviewed in sun yat-sen memorial hospital from 1996 to 2012. da...

Background and aims: Loneliness typically includes anxious feelings. It is particularly relevant to adolescence period. It has effect on physical and mental health. The present study aimed to identify the predictive factors of loneliness among high schools female students. Methods: A cross– sectional survey was carried out among high schools female students in Ilam during the academic year 201...

     Salt crystallization is one of the most powerful weathering agents that may cause a rapid change in the mechanical properties of stones, and thus limit their durability. Consequently, determining the mechanical properties of stones due to salt crystallization is important for natural building stones used in marine environmental and mild climatic conditions, which expose excessive salt crys...

We consider recovering the jointly sparse multichannel signals from incomplete and noisy measurements. We take the approach of penalized least squares with the penalty given by the ell2,1 norm of the unknown regression coefficients. In contrast to recent efforts on the worstcase analysis, the average case analysis demonstrates more optimistic support recovery results under weaker assumptions. A...

AIM To identify the risk factors relating to early mortality after orthotopic liver transplantation. METHODS Clinical data of 37 adult patients undergoing liver transplantation were retrospectively collected and divided into two groups: the survived group and the death group (survival time<30 d). The relationship between multivariate risk factors and early mortality after orthotopic liver tra...

Genetic studies of complex diseases often collect multiple phenotypes relevant to the disorders. As these phenotypes can be correlated and share common genetic mechanisms, jointly analyzing these traits may bring more power to detect genes influencing individual or multiple phenotypes. Given the advancement brought by the multivariate phenotype approaches and the multimarker kernel machine regr...

Making inferences about the average treatment effect using the random effects model for meta-analysis is problematic in the common situation where there is a small number of studies. This is because estimates of the between-study variance are not precise enough to accurately apply the conventional methods for testing and deriving a confidence interval for the average effect. We have found that ...
