ABSTRACT We discuss here an alternative approach for decreasing the bias of the closed-form estimators for the gamma distribution recently proposed by Ye and Chen in 2017. We show that, the new estimator has also closed-form expression, is positive, and can be computed for n > 2. Moreover, the corrective approach returns better estimates when compared with the former ones. 

A score-adjusted approach to closed-form estimators for the gamma and beta distributions

The closed-form estimators proposed by Ye and Chen (Am Stat 71(2):177–181, 2017) for the gamma distribution can be derived by the score-adjusted method, and in the orthogonal reparameterization, the

A modified closed-form maximum likelihood estimator

The maximum likelihood estimator plays a fundamental role in statistics. However, for many models, the estimators do not have closed-form expressions. This limitation can be significant in situations

On point estimators for Gamma and Beta distributions

Let X 1 , . . . , X n be a random sample from the Gamma distribution with density f ( x ) = λ α x α − 1 e − λ x / Γ ( α ), x > 0, where both α > 0 (the shape parameter) and λ > 0 (the reciprocal

Objective Bayesian inference for the capability index of the Gamma distribution

The Gamma distribution has been applied in research in several areas of knowledge, due to its good flexibility and adaptability nature. Process capacity indices like Cpk are widely used when the

Closed-Form Estimators for the Gamma Distribution Derived From Likelihood Equations

ABSTRACT It is well-known that maximum likelihood (ML) estimators of the two parameters in a gamma distribution do not have closed forms. This poses difficulties in some applications such as

Improved maximum-likelihood estimation of the shape parameter in the Nakagami distribution

We develop and evaluate analytic and bootstrap bias-corrected maximum-likelihood estimators for the shape parameter in the Nakagami distribution. This distribution is widely used in a variety of

A General Definition of Residuals

RESIDUALS are now widely used to assess the adequacy of linear models; see Anscombe (1961) for a systematic discussion of significance tests based on residuals, and for references to earlier work. A

Inequalities for the polygamma functions with application 1

We present some inequalities for the polygamma funtions. As an application, we give the upper and lower bounds for the expression n k=1 1 k − ln n − γ, where γ = 0.57721 · · · is the Euler's
