Moments of Dual Generalized Order Statistics from Inverted Kumaraswamy Distribution and Related Inference

Journal of Statistical Theory and Applications (JSTA), 2021
In this paper, the exact and explicit expressions for single, product, and conditional moments for inverted Kumaraswamy distribution using dual generalized order statistics (dgos) are derived. Further, the expression for maximum likelihood estimator (MLE)

Linear Spaces and Minimum Variance Unbiased Estimation [PDF]

The Annals of Mathematical Statistics, 1971
Consideration is given to minimum variance unbiased estimation when the choice of estimators is restricted to a finite-dimensional linear space. The discussion gives generalizations and minor extensions of known results in linear model theory utilizing both the coordinate-free approach of Kruskal and the usual parametric representations.

Sample Design and Estimation of Parameters of Half Logistic Distribution Using Generalized Ranked-Set Sampling

Journal of Statistical Theory and Applications (JSTA), 2020
The ranked-set sampling technique has been generalized so that a more efficient estimator may be obtained. This technique allows more than one unit from each set to be quantified.

A Unified Filter for Simultaneous Input and State Estimation of Linear Discrete-time Stochastic Systems [PDF]

, 2014
In this paper, we present a unified optimal and exponentially stable filter for linear discrete-time stochastic systems that simultaneously estimates the states and unknown inputs in an unbiased minimum-variance sense, without making any assumptions on ...

What you can do with Coordinated Samples [PDF]

, 2013
Sample coordination, where similar instances have similar samples, was proposed by statisticians four decades ago as a way to maximize overlap in repeated surveys. Coordinated sampling had been since used for summarizing massive data sets.
