BACKGROUND AND OBJECTIVES: The classification of marine animals as protected species makes data and information on them to be very important. Therefore, this led to the need to retrieve and understand the data on the event counts for stranded marine animals based on location emergence, number of individuals, behavior, and threats to their presence. Whales are g...

The goal of this study is to introduce a statistical method regarding the analysis of specific latent data for regression analysis of the discrete data and to build a relation between a probit regression model (related to the discrete response) and normal linear regression model (related to the latent data of continuous response). This method provides precise inferences on binary and multinomia...

toxoplasmosis is one of the most common parasitic diseases worldwide. although estimated that one third of the world's population are infected with toxoplasma gondii , but the most common form of the disease is latent (asymptomatic). on the other hand, recent findings indicated that la­tent toxoplasmosis is not only unsafe for human, but also may play various roles in the etiol­ogy of different...

Latent Gaussian models are flexible models that are applied in several statistical applications. When posterior marginals or full conditional distributions in hierarchical Bayesian inference from these models are not available in closed form, Markov chain Monte Carlo methods are implemented. The component dependence of the latent field usually causes increase in computational time and divergenc...

One of the recommended strategies for preventing tuberculosis is to screen high-risk populations with respect to Mycobacterium tuberculosis (TB) infection. The aim of the present study was to investigate latent infection and active tuberculosis in people with close household contact. It was a cross-sectional descriptive, analytical study with the sample size of 668 people from homes with one in...

the aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (nepcm) slurry as a cooling fluid instead of pure fluid. a threedimensional model of a circular channel using water slurry of nepcm was developed. the results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...

purpose: to present a case of spontaneous resolution of essential esotropia case report: a 22-month-old girl presented with eye deviation since the age of 4 month. in the first examination, visual acuity of both eyes was c+s+m+. the patient had 35 prism diopters of alternative esotropia in primary position and also bilateral inferior oblique overaction (iooa). there was no significant refractiv...

conclusions fib-4 confirmed the best value for diagnosis of significant fibrosis. apri had a sub-optimal diagnosis accuracy for significant fibrosis. lsm showed the most balance diagnosis value for cirrhosis with the highest sensitivity and moderate specificity. patients and methods a total of 544 patients with chb were assessed for fibrosis stage by four noninvasive tests containing liver stif...

 Spatial generalized linear mixed models are used commonly for modelling non-Gaussian discrete spatial responses. We present an algorithm for parameter estimation of the models using Laplace approximation of likelihood function. In these models, the spatial correlation structure of data is carried out by random effects or latent variables. In most spatial analysis, it is assumed that rando...

The goal of this study was to present a model with Islamic approach for the organization. To achieve this goal, a conceptual model of research designed. This model includes four latent variables. Each one of these latent variables has observed variables. On the basis of the conceptual model, the questionnaire for the measurements of the variables was composed. The statistic society of this rese...
