New Approaches on Parameter Estimation of the Gamma Distribution

چکیده
This paper discusses new approaches to parameter estimation of gamma distribution based on representative points. In the first part, existence and uniqueness mean squared error points (MSE-RPs) are discussed theoretically. second by comparing three types points, we show that MSE-RPs perform well in simulation. The last part proposes a Harrel–Davis sample standardization technique. Simulation studies reveal standardized samples can be used improve performance or generate MSE-RPs. addition, real data analysis illustrates proposed technique yields efficient estimates for parameters.

Parameter Estimation in Multivariate Gamma Distribution
Multivariate gamma distribution finds abundant applications in stochastic modelling, hydrology and reliability. Parameter estimation in this distribution is a challenging one as it involves many parameters to be estimated simultaneously. In this paper, the form of multivariate gamma distribution proposed by Mathai and Moschopoulos [9] is considered. This form has nice properties in terms of mar...

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولESTIMATION OF SCALE PARAMETER UNDER A REFLECTED GAMMA LOSS FUNCTION
In this paper, the estimation of a scale parameter t under a new and bounded loss function, based on a reflection of the gamma density function, is discussed. The best scale-invariant estimator of tis obtained and the admissibility of all linear functions of the sufficient statistic, for estimating t in the absence of a nuisance parameter, is investigated
متن کاملEntropy-Based Parameter Estimation for the Four-Parameter Exponential Gamma Distribution
Two methods based on the principle of maximum entropy (POME), the ordinary entropy method (ENT) and the parameter space expansion method (PSEM), are developed for estimating the parameters of a four-parameter exponential gamma distribution. Using six data sets for annual precipitation at the Weihe River basin in China, the PSEM was applied for estimating parameters for the four-parameter expone...
متن کاملAdmissible Estimators of ?r in the Gamma Distribution with Truncated Parameter Space
In this paper, we consider admissible estimation of the parameter ?r in the gamma distribution with truncated parameter space under entropy loss function. We obtain the classes of admissible estimators. The result can be applied to estimation of parameters in the normal, lognormal, pareto, generalized gamma, generalized Laplace and other distributions.
