Estimation for scale parameter of type-I extreme value distribution

Estimation for the Type-II Extreme Value Distribution Based on Progressive Type-II Censoring

In this paper, we discuss the statistical inference on the unknown parameters and reliability function of type-II extreme value (EVII) distribution when the observed data are progressively type-II censored. By applying EM algorithm, we obtain maximum likelihood estimates (MLEs). We also suggest approximate maximum likelihood estimators (AMLEs), which have explicit expressions. We provide Bayes ...

Parameter estimation for the general extreme value distribution

This study is concerned with the estimation of the parameters of the general (or generalised) extreme value (GEV) distribution by the methods of maximum likelihood (ML) and probability-weighted moments (PWM) for complete and type I censored samples. For complete samples, the PWM provided estimators which are less biased than the ML estimators. For the variances/covariances of the parameter esti...

Estimation of Lower Bounded Scale Parameter of Rescaled F-distribution under Entropy Loss Function

We consider the problem of estimating the scale parameter &beta of a rescaled F-distribution when &beta has a lower bounded constraint of the form &beta&gea, under the entropy loss function. An admissible minimax estimator of the scale parameter &beta, which is the pointwise limit of a sequence of Bayes estimators, is given. Also in the class of truncated linear estimators, the admissible estim...

On Shrinkage Estimation for the Scale Parameter of Weibull Distribution

In the present article, some shrinkage testimators for the scale parameter of a two – parameter Weibull life testing model have been suggested under the LINEX loss function assuming the shape parameter is to be known. The comparisons of the proposed testimators have been made with the improved estimator.
