http://www.redalyc.org/articulo.oa?id=89940050004
The alpha-skew normal (ASN) distribution has been proposed recently in the literature by using standard normal distribution and a skewing approach. Although ASN distribution is able to model both ...A Bimodal Extension of the Generalized Gamma Distribution
http://www.redalyc.org/articulo.oa?id=89940050003
A bimodal extension of the generalized gamma distribution is proposed by using a mixing approach. Some distributional properties of the new distribution are investigated. The maximum likelihood (M ...Design of SkSP-R Variables Sampling Plans
http://www.redalyc.org/articulo.oa?id=89940050007
In this paper, we present the designing of the skip-lot sampling plan including the re-inspection called SkSP-R .The plan parameters of the proposed plan are determined through a nonlinear optimiz ...Global Polynomial Kernel Hazard Estimation
http://www.redalyc.org/articulo.oa?id=89940050006
This paper introduces a new bias reducing method for kernel hazard estimation. The method is called global polynomial adjustment (GPA). It is a global correction which is applicable to any kernel ...Fundamental Concepts on Classification and Statistical Implicative Analysis for Modal Variables
http://www.redalyc.org/articulo.oa?id=89940050002
The present work offers some fundamental concepts of the Statistical Implicative Analysis for modal variables and proposes an index to establish the similarity between two modal variables. Express ...Bayesian Analysis of the 3-Component Mixture of Exponential Distribution Assuming the Non-Informative Priors
http://www.redalyc.org/articulo.oa?id=89940050008
Bayesian analysis of the 3-component mixture of an Exponential distribution under type-I right censoring scheme is considered in this paper. The Bayes estimators and posterior risks for the unknow ...Parameter Estimation of Power Function Distribution with TL-moments

Combining Some Biased Estimation Methods with Least Trimmed Squares Regression and its Application
http://www.redalyc.org/articulo.oa?id=89940050011
In the case of multicollinearity and outliers in regression analysis, the researchers are encouraged to deal with two problems simultaneously. Biased methods based on robust estimators are useful ...Classical and Bayesian Estimation of Reliability in Multicomponent Stress-Strength Model Based on Weibull Distribution
http://www.redalyc.org/articulo.oa?id=89940050010
In this study, we consider a multicomponent system which has k independent and identical strength components X1; ... ;Xk and each component is exposed to a common random stress Y when the underlyi ...Slashed Exponentiated Rayleigh Distribution
http://www.redalyc.org/articulo.oa?id=89940050009
In this paper we introduce a new distribution for modeling positive data with high kurtosis. This distribution can be seen as an extension of the exponentiated Rayleigh distribution. This extensio ...A Note on Generalized Exponential Type Estimator for Population Variance in Survey Sampling
http://www.redalyc.org/articulo.oa?id=89940050005
Recently a new generalized estimator for population variance using information on the auxiliary variable has been introduced by Asghar, Sanaullah :& Hanif (2014). In that paper there was some ...
