[ 1 ] - The Uniform-Pareto Distribution and Eeponentiated Uniform-Pareto Distribution and Their Application in Income Data

‎In this paper‎, ‎a new distribution is introduced‎, ‎which is a generalization of a well-known distribution‎. ‎This distribution is flexible and applies to income data modeling‎. ‎We first provide some of the mathematical and distributional properties of this new model and then‎, ‎to demonstrate the flexibility the new distribution‎, ‎we will present the applications of this distribution with ...

[ 2 ] - Providing of some family of continuous distributions to fit the best distribution on drought data of Guilan state and investigation of duration of the drought on this stat

In this paper, after stating the characteristicof some of continuous distributions including, gamma, Crovelli’s gamma, Rayleigh, Weibull, Pareto, exponential and generalized gamma distribution with each other,these distributions were fit on drought data of Guilan state and the best distribution was presented. Then, severity and duration of the drought of different sites were investigated usi...

[ 3 ] - application of crovelli's bivariate gamma distribution in hydrological processes

Mathematical methods and statistical distributions present exact results in the climate calculations and hydrological processes. Awareness of the rainfall probability distribution provides the appropriate conditions for water resource planning. Many studies have been done to estimate probability of rainfall by various methods due to the importance of rainfall distribution in the economic, soci...

[ 4 ] - A NEW FOUR-PARAMETER DISTRIBUTION: PROPERTIES AND APPLICATIONS

In this paper a new four-parameter lifetime distribution named “the Exponentiated gompertz-poisson (E-GP) distribution” has been suggested that it has a decreasing, increasing, bathtub-shaped and inverse bathtub-shape for modeling lifetime data. The Exponentiated gompertz-poisson has applications in economics, actuarial modelling,reliability modeling, lifetime and queuing problems and biologica...

[ 5 ] - A New Five-Parameter Distribution: Properties and Applications

In this paper, a new five-parameter lifetime and reliability distribution named “the exponentiated Uniform-Pareto distribution (EU-PD),” has been suggested that it has a bathtub-shaped and inverse bathtub-shape for modeling lifetime data. This distribution has applications in economics, actuarial modelling, reliability modeling, lifetime and biological sciences. Firstly, the mathematical and st...

[ 6 ] - The Exponentiated Poisson-Lindley Distribution; Features and Applications in Reliability

Abstract. In this paper a new three-parameter lifetime distribution named “the Exponentialed Lindley-Poisson (E-LP) distribution” has been suggested that it has an increasing, decreasing and invers bathtube hazard rate depending on the parameter values. The (E-LP) distribution has applications in economics, actuarial modeling, reliability modeling, lifetime and queuing problems and biological ...

[ 7 ] - Statistical Study to Find the Optimal Dose of the First Phase in Leukemia Patients

Abstract. In this paper, a structured framework for determining the optimal dose of the first phase in leukemia patients is presented. And here we describe and discuss the key parameters that are needed to set up and run a CRM trial. These are: number of doses; maximum tolerable dose; Target Toxicity Level Dose-toxicity model; Dose-toxicity skeleton; Sample size and cohort size and Stopping ru...
