The dynamichazard package implements state space models that can provide a computationally efficient way to model time-varying parameters in survival analysis. I cover the and some of estimation methods implemented dynamichazard, apply them large data set, perform simulation study illustrate methods' computation time performance. One is compared with other R which allow for left-truncation, rig...

in this paper, we apply the biswas’ idea of anti fuzzy subgroups toideals of near-rings. we introduce the notion of anti fuzzy ideals of near-rings,and investigate some related properties.

Background Celiac disease (CD) is an autoimmune mediated gluten sensitive enteropathy and characterized by a wide range of clinical manifestations. The study aimed to compare Doppler tissue echocardiography findings between children with celiac disease and healthy children. Materials and Methods This case-control study was performed on 186 celiac and healthy children aged 6- 19 years.  Celiac d...

  Multiple criteria decision making (MCDM) problem is one of the famous different kinds of decision making problems. In more cases in real situations, determining the exact values for MCDM problems is difficult or impossible. So, the values of alternatives with respect to the criteria or / and the values of criteria weights, are considered as fuzzy values (fuzzy numbers). In such conditions, th...

In survival analysis, epidemiology and related fields there exists an increasing interest in statistical methods for doubly truncated data. Double truncation appears with interval sampling other schemes, refers to situations which the target variable is subject two (left right) random observation limits. Doubly data require specific corrections observational bias, this affects a variety of sett...

background: one of the important etiologies for cryptogenic stroke is paradoxical embolization secondary to patent foramen ovale (pfo). foramen ovale can secondarily reopen due to pulmonary arterial hypertension (pah) which is common among the older age. pah is known as a frequent and life threatening complication of copd. the aim of this study was to determine the prevalence of pfo between cop...
