Local Mixtures of the Negative Exponential Distribution
نویسندگان
چکیده
A new class of local mixture models called local scale mixture models is introduced here. This class is particularly suitable for the analysis of mixtures of the negative exponential distribution. The affine structure revealed by specific asymptotic expansions is the motivation for the construction of these models. They are shown to have very nice statistical properties which are exploited to make inferences in a straightforward way. The effect on inference of a new type of boundaries, called soft boundaries, is analyzed. A simple simulation study shows the applicability of this type of models.

Sequential estimation of linear combinations of the location and scale parameters in negative exponential distribution
Sequential estimation is used where the total sample size is not fix and the problem cannot solve with this fixed sample size. Sequentially estimating the mean in an exponential distribution (one and two parameter), is an important problem which has attracted attentions from authors over the years. These largely addressed an exponential distribution involving a single or two parameters. In t...
متن کاملImpacts of the Negative-exponential and the K-distribution modeled FSO turbulent links on the theoretical and simulated performance of the distributed diffusion networks
Merging the adaptive networks with the free space optical (FSO) communication technology is a very interesting field of research because by adding the benefits of this technology, the adaptive networks become more efficient, cheap and secure. This is due to the fact that FSO communication uses unregistered visible light bandwidth instead of the overused radio spectrum. However, in spite of all ...
متن کاملPerishable Inventory Model with Retrial Demands, Negative Customers and Multiple Working Vacations
This paper presents the analysis of a continuous review perishable inventory system wherein the life time of each item follows an exponential distribution. The operating policy is (s,S) policy where the ordered items are received after a random time which follows exponential distribution. Primary arrival follows Poisson distribution and they may turnout to be posit...
متن کاملProbability Distribution Fitting to Maternal Mortality in Nigeria.
The consequences of Maternal Mortality (MM) cannot be overemphasized. It inhibits population growth resulting into loss of lives among others. This work tends to obtain the maternal mortality rates (MMR) in Nigeria, identify some fitted distributions to MMR and determine which of the distributions best fits the data. A comprehensive Exploratory Data Analysis (EDA) was carried on MM and the MMRs...

*Correspondence: [email protected] 1Department of Mathematics, Ohio University, Athens, OH, USA Full list of author information is available at the end of the article Abstract Poisson-Tweedie mixtures are the Poisson mixtures for which the mixing measure is generated by those members of the family of Tweedie distributions whose support is non-negative. This class of non-negative integer-valued ...
