AN EXTENSION OF THE TWO-PARAMETER WEIBULL DISTRIBUTION UNA EXTENSIÓN DE LA DISTRIBUCIÓN WEIBULL DE DOS PARÁMETROS

Revista Colombiana de Estadística, 2010
In this paper, we present an extension of the Two-parameter Weibull distribution to make it even more flexible in terms of its kurtosis coefficient. Properties involving moments and asymmetry and kurtosis indexes are studied.

Threshold Stochastic Volatility Models with Heavy Tails: A Bayesian Approach

Economía, 2019
This paper extends the threshold stochastic volatility (THSV) model specification proposed in So et al. (2002) and Chen et al. (2008) by incorporating thick-tails in the mean equation innovation using the scale mixture of normal distributions (SMN).

A role of the mechanical preparation of soil in the natural regeneration of pedunculate oak (Quercus robur L.) in floodplain forests

Journal of Forest Science, 2005
The subject of our research was to verify effects of the mechanical preparation of soil in the natural regeneration of pedunculate oak in a floodplain forest. On the site of a hard-wooded floodplain forest at the confluence of the Morava and Dyje rivers (

A Versatile Distribution Based on the Incomplete Gamma Function: Characterization and Applications

Mathematics
In this study, we introduce a novel distribution related to the gamma distribution, referred to as the generalized incomplete gamma distribution. This new family is defined through a stochastic representation involving a linear transformation of a random

Microbial biomass and soil chemical properties under different land use systems in northeastern Pará

Revista Brasileira de Ciência do Solo, 2011
The increase in agricultural production in the Brazilian Amazon region is mostly a result of the agricultural frontier expansion, into areas previously influenced by humans or of native vegetation.

On Generalized Slash Distributions: Representation by Hypergeometric Functions [PDF]

Stats, 2019
The popular concept of slash distribution is generalized by considering the quotient Z = X/Y of independent random variables X and Y, where X is any continuous random variable and Y has a general beta distribution. The density of Z can usually be expressed by means of generalized hypergeometric functions.
