On the basis of the half-Cauchy distribution, we propose the called beta-half-Cauchy distribution for modeling lifetime data. Various explicit expressions for its moments, generating and quantile functions, mean deviations, and density function of the order statistics and their moments are provided. The parameters of the new model are estimated by maximum likelihood, and the observed informatio...

Chia (Salvia hispanica L.) is one of the most important medicinal plants recently introduced to Egyptian cultivation and has significant multiusing in human curing. Fusarium oxysporum, F. roseum, semitectum, solani, Macrophomina phaseolina, Pythium ultimum, Rhizoctonia solani Sclerotinia sclerotiorum were isolated from infected plants, showing root stem rot symptoms collected different localiti...

BACKGROUND Registry data from four major public hospitals indicate trends in clinical care and survival from colorectal cancer over three decades, from 1980 to 2010. MATERIALS AND METHODS Kaplan-Meier product- limit estimates and Cox proportional hazards models were used to investigate disease-specific survival and multiple logistic regression analyses to explore first-round treatment trends....

We study estimation and model selection of semiparametric models of multivariate survival functions for censored data, which are characterized by possibly misspecified parametric copulas and nonparametric marginal survivals. We obtain the consistency and root-n asymptotic normality of a two-step copula estimator to the pseudo-true copula parameter value according to KLIC, and provide a simple c...

Stroke (Cerebral vascular accident, CVA) is a common and serious disease. Most of the survivals would be disabled after their illness recovery, causes serious burden on caregivers. It is said that rehabilitation could help functional recovery of stroke patients, regain independence after stroke. Due to the long course of stroke, how to prevent survivals from recurrence is an important issue. Th...

Standard economic models assume that the weight given to information from different sources depends exclusively on its diagnosticity. In this paper we study whether the same piece of information is weighted more heavily simply because it arose from direct experience rather than from observation. We investigate this possibility by conducting repeated game experiments in which groups of players a...
