EM Algorithm in the Slash 2S-Lindley Distribution with Applications

Axioms
In this work, we present a new distribution, which is a slash extension of the distribution of the sum of two independent Lindley random variables. This new distribution is developed using the slash methodology, resulting in a distribution with more ...

Modified slash Birnbaum-Saunders distribution

Hacettepe Journal of Mathematics and Statistics, 2016
Summary: In this paper, we introduce an extension for the Birnbaum-Saunders (BS) distribution based on the modified slash (MS) distribution proposed by \textit{J. Reyes} et al. [Statistics 47, No. 5, 929--941 (2013; Zbl 1440.62054)]. This new family of BS type distributions is obtained by replacing the usual normal distribution with the quotient of two

Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]

, 2005
The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

Modeling the risk of illegal forest activity and its distribution in the southeastern region of the Sierra Madre Mountain Range, Philippines

iForest - Biogeosciences and Forestry, 2022
Illegal activity within protected forests, such as illegal logging, slash-and-burn farming, and agricultural expansion, has brought many plant and animal species to the brink of extinction and threatens various conservation efforts.

On univariate slash distributions, continuous and discrete [PDF]

Annals of the Institute of Statistical Mathematics, 2019
The author investigates general properties of random variables of the form \(Y/U\) (the so-called slash distributions), where \(Y\) and \(U\) are independent random variables with \(Y\) supported on \(\mathbb{R}^+\) and \(U\) uniformly distributed on \((0,1)\), and the more general \(\alpha\)-slash distributions of the form \(Y_\alpha/U^{1/\alpha}\), \(

Characterizing Fusiform Rust Incidence and Distribution in East Texas [PDF]

, 1994
Three measurement cycles were completed on an extensive network of loblolly( Pinus taeda L.) pine and slash (Pinus elliottii Engelm.) pine plots in industrial plantations throughout East Texas in 1984, 1987, and 1990.Because the incidence of fusiform ...

The effects of vegetation type on ecosystem carbon storage and distribution in subtropical plantations

Frontiers in Forests and Global Change, 2023
Establishing plantation forests significantly increases the carbon (C) storage of terrestrial ecosystems. However, how vegetation types affect the ecosystem C sequestration capacity is not completely clear.

A New Diameter Distribution Model for Unmanaged Slash Pine Plantations in East Texas [PDF]

, 2008
A parameter recovery procedure for the Weibull distribution function based on four percentile equations was used to develop a new diameter distribution yield prediction model for unmanaged slash pine (Pinus elliottii Engelm.) plantations in East Texas ...

The Location-Scale Mixture Exponential Power Distribution: A Bayesian and Maximum Likelihood Approach

Journal of Applied Mathematics, 2012
We introduce an alternative skew-slash distribution by using the scale mixture of the exponential power distribution. We derive the properties of this distribution and estimate its parameter by Maximum Likelihood and Bayesian methods.

Properties and Applications of some Distributions derived from Frullani's integral [PDF]

, 2014
Frullani's integral dates from 1821, but a probabilistic interpretation of it has never been made. In this paper, Frullani's integral formula is shown to result from mixing a lifetime distribution by allowing the logarithm of the scale factor to be ...
