In the model of type I censored exponential lifetimes, coverage probabilities are compared for a number of confidence interval constructions proposed in literature. The coverage probabilities are calculated exactly for sample sizes up to 50 and for different degrees of censoring and different degrees of intended confidence. If not only a fair two-sided coverage is desired, but also fair one-sid...

Multicomponent stress–strength reliability (MSR) is explored for the system with Burr XII distributed components under Type-II censoring. When distributions of strength and stress variables have common or unequal inner shape parameters, existence uniqueness maximum likelihood estimators are investigated established. The associated approximate confidence intervals obtained by using asymptotic no...

The aim of statistical modeling is to identify the model that most closely approximates the underlying process. Akaike information criterion (AIC) is commonly used for model selection but the precise value of AIC has no direct interpretation. In this paper we use a normalization of a difference of Akaike criteria in comparing between the two rival models under unified hybrid cens...

In this article, we consider statistical inferences about the unknown parameters of Lomax distribution basedon Adaptive Type-II Progressive Hybrid censoring scheme, scheme can save both total test time and cost induced by failure units increases efficiency analysis. The estimation is derived using maximum likelihood (MLE) Bayesian procedures. estimators are obtained based on symmetric asymmetri...

In this paper, we present a method to construct rate-compatible convolutional (RCC) codes from known high-rate punctured convolutional codes, obtained from best-rate 1/2 codes. The construction method is rather simple and straightforward, and still yields good codes. Moreover, low rate codes can be obtained without any limit on the lowest achievable code rate. Based on the RCC codes, a generali...

This paper provides the estimation of the scale parameter of the exponential distribution under multiply type-II censoring. Using generalized non-informative prior and natural conjugate prior, Bayes estimator and approximate Bayes estimators of the scale parameter have been obtained under square error loss function. The proposed Bayes estimators and approximate Bayes estimators are compared wit...
