In this paper we consider the weighted exponential distribution proposed by Gupta and Kundu (Statistics 43:621–634, 2009) and discuss its various reliability properties. We further consider the length biased version of the weighted exponential distribution, and discuss different properties and inferential issues. The maximum likelihood estimators of the unknown parameters of the proposed length biased...
In this article, we introduce a new three-parameter skewed distribution of which normal distribution is a special case. This distribution is obtained by using geometric sum of independent identically distributed normal random variables. We call this distribution as the geometric skew normal distribution. Different properties of this new distribution have been investigated. The probability density...
