A new probability distribution, the xgamma is proposed and studied. The distribution generated as a special finite mixture of exponential gamma distributions hence name proposed. Various mathematical, structural, survival properties are derived, it found that in many cases has more flexibility than distribution. To evaluate comparative behavior, stochastic ordering estimate model parameter, method moment maximum likelihood estimation simulation algorithm to generate random samples from...
One of the indicators for evaluating capability a process is index. In this article, bootstrap confidence intervals generalized index (GPCI) proposed by Maiti et al. are studied through simulation, when underlying distributions Lindley and Power distributions. The maximum likelihood method used to estimate parameters models. Three namely, standard (SB), percentile (PB), bias-corrected (BCPB) considered obtaining GPCI. A Monte Carlo simulation has been investigate estimated coverage...
A generalized process capability index, defined as the ratio of proportion specification conformance (or, yield) to desired natural) conformance, has been developed. Almost all capabilities in literature are directly or indirectly associated with this index. Normal well non-normal and continuous discrete random variables could be covered by new It can also assessed under either unilateral bilateral specifications. We deal proposed index case normal, exponential Poisson processes. Under each...
Abstract In this article, we consider six process capability indices (PCIs) whose quality characteristics have a normal distribution, out of which first PCI <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"> <m:msub> <m:mi mathvariant="script">𝒞</m:mi> <m:mi>p</m:mi> </m:msub> </m:math> {\mathcal{C}_{p}} was developed in [J.

Rapid micropropagation was achieved in Chlorophytum borivilianum Santapau and Fernandes using shoot base as explants. Multiple shoots were induced on Murashige Skoog's (MS) medium supplemented with 3.0 mg dm-3 6-benzylaminopurine, 0.1 1-naphthaleneacetic acid, 150 adenine sulphates 3 % saccharose. Rooting readily upon transferring the onto half strength MS indolebutyric acid 2 Micropropagated plantlets hardened greenhouse successfully established soil. Random amplified polymorphic DNA (RAPD)...
For enhancing the quality and productivity, use of process capability index (PCI) has become significant in statistical control, designed to quantify relation between actual performance its specified requirements. Confidence interval is an important part PCI because it estimated value provides much more information about population characteristic interest than does a point estimate. In this article, bootstrap confidence intervals non-normal , studied through simulation when underlying...
In this article, we have investigated some further distributional properties (such as, characteristic and generating functions, distributions of extreme order statistics, important entropy measures) additional survival and/or reliability characteristics time to failure, ageing in tensity, stress-strength reliability) one parameter xgamma distribution which serves as an useful model. We also studied the estimation procedures model its considering maximum likelihood Bayesian techniques under...
A new distribution, called Odds Generalized Exponential-Exponential distribution (OGEED) is proposed for modeling lifetime data. comprehensive account of the mathematical properties including estimation and simulation issues presented. data set has been analyzed to illustrate its applicability.
This article addresses two methods of estimation the probability density function (PDF) and cumulative distribution (CDF) for Lindley distribution. Following are considered: uniformly minimum variance unbiased estimator (UMVUE) maximum likelihood (MLE). Since is more flexible than exponential distribution, same estimators have been found out compared. Monte Carlo simulations a real data analysis performed to compare performances proposed estimation.
Process capability indices (PCIs) aim to quantify the of a process quality characteristic ( X ) meet some specifications that are related measurable its produced items. One such is life time The determined through lower specification limit L ), upper U and target value T ). Maiti et al. (2010) have proposed generalized index ratio proportion conformance desired conformance. Bayesian estimation has been considered under squared error loss function. Normal, exponential (nonnormal), Poisson...
In this paper, we present a new family, depending on additive Weibull random variable as generator, called the generalized generated-family (GAW-G) of distributions with two extra parameters. The proposed family involves several most famous classical well Weibull-G which already accomplished by Cordeiro et al. (2015). Four special models are displayed. expressions for incomplete and ordinary moments, quantile, order statistics, mean deviations, Lorenz Benferroni curves derived. Maximum...
A new leaf rot disease of Aloe vera was observed for the first time in 2000, at National Research Centre Medicinal and Aromatic Plants, India. The serious when abundant moisture available through irrigation and/or rain. symptoms started as water-soaked lesions base leaves. rotting progressed very fast whole plant died within 2–3 days. As progressed, epidermis bulged out due to gas formation content converted a slimy mass, which eventually released. bacterium isolated from infected tissues....

SYNOPTIC ABSTRACTProcess capability indices (PCIs) have been widely applied in measuring product potential and performance. It is of great significance to quality control engineers, as it quantifies the relation between actual performance process preset specifications product. Among plethora suggested PCIs, most them were developed for normally distributed processes. In this article, we consider generalized index Cpy by Maiti et al. (2010 Maiti, S. S., Saha, M., & Nanda, A. K. (2010). On...
