Background N-terminal pro–B-type natriuretic peptide (NT-proBNP) is a marker to evaluate the cardiac involvement in thalassemia. We aimed to evaluate conventional and tissue Doppler echocardiography findings and its relation to plasma NT-pro BNP, Ferritin and Iron levels in beta-thalassemia patients. Materials and Methods This study performed on 164 participants equal of major beta- thalassemi...

Due to the advance computer technology, use of probability distributions has been raised up solve real life problems. These applications are found in reliability engineering, sciences, economics, psychology, survival analysis, and some others. This study offers a new model called Marshall–Olkin Extended Gumbel Type-II (MOEGT-II) which can various shapes failure rate function. The proposed distr...

We consider the problem of decentralized detection in a sensor network consisting of nodes arranged as a tree of bounded height. We characterize the optimal error exponent under a Neyman-Pearson formulation, and show that the Type II error probability decays exponentially with the number of nodes. Surprisingly, the optimal error exponent is often the same as that corresponding to a parallel con...

When students obtain a statistically significant sample at a 5% level of significance, they may conclude they can be 95% confident that the alternate hypothesis is true. From a classical perspective, this conclusion is unwarranted. Two elements may inadvertently support this unwarranted conclusion: the traditional definitions of Type I error and alpha, and the silence about confidence. From a B...

We propose a nonparametric sequential test that aims to address two practical problems pertinent to online randomized experiments: (i) how to do a hypothesis test for complex metrics; (ii) how to prevent type 1 error inflation under continuous monitoring. The proposed test does not require knowledge of the underlying probability distribution generating the data. We use the bootstrap to estimate...

The firstand second-order optimum achievable exponents in the simple hypothesis testing problem are investigated. The optimum achievable exponent for type II error probability, under the constraint that the type I error probability is allowed asymptotically up to ε, is called the ε-optimum exponent. In this paper, we first give the second-order ε-optimum exponent in the case where the null hypo...

A minimax converse for the identification via channels is derived. By this converse, a general formula capacity, which coincides with transmission proved without assumption of strong property. Furthermore, optimal second-order coding rate characterized when type I error probability non-vanishing and II vanishing. Our built upon so-called partial channel resolvability approach; however, argument...

In this paper, we discuss the statistical inference on the unknown parameters and reliability function of type-II extreme value (EVII) distribution when the observed data are progressively type-II censored. By applying EM algorithm, we obtain maximum likelihood estimates (MLEs). We also suggest approximate maximum likelihood estimators (AMLEs), which have explicit expressions. We provide Bayes ...
