Estimating the polarization degree of polarimetric images in coherent illumination using maximum likelihood methods [PDF]
, 2009 This paper addresses the problem of estimating the polarization degree of polarimetric images in coherent illumination. It has been recently shown that the degree of polarization associated to polarimetric images can be estimated by the method of moments

Statistica, 2018 The problem of estimating the mean matrix of a matrix-variate normal distribution with a covariance matrix is considered under two loss functions. We construct a class of empirical Bayes estimators which are better than the maximum likelihood estimator ...

Maximum Likelihood Estimation of Position in GNSS [PDF]
IEEE Signal Processing Letters, 2007 In this letter, we obtain the Maximum Likelihood Estimator of position in the framework of Global Navigation Satellite Systems. This theoretical result is the basis of a completely different approach to the positioning problem, in contrast to the conventional two-steps position estimation, consisting of estimating the ...

, 2017 The success of any predictive model is largely dependent on the accuracy with which its parameters are known. When characterising fracture networks in rocks, one of the main issues is accurately scaling the parameters governing the distribution of ...

Variable bandwidth local maximum likelihood type estimation for diffusion processes
Advances in Difference Equations, 2018 The method of robust approach is applied to estimate drift function and diffusion function of diffusion processes with discrete-time observations. The proposed method combines the ideas of local linear regression technique and maximum likelihood type ...

Bias-Corrected Maximum Likelihood Estimators of the Parameters of the Unit-Weibull Distribution
Austrian Journal of Statistics, 2021 It is well known that the maximum likelihood estimates (MLEs) have appealing statistical properties. Under fairly mild conditions their asymptotic distribution is normal, and no other estimator has a smaller asymptotic variance.

Estimations of Modified Lindley Parameters Using Progressive Type-II Censoring with Applications
Axioms, 2023 This study addresses the estimation problems of the modified Lindley distribution using a progressive Type-II censoring plan. Using the maximum likelihood and maximum product of spacing and Bayesian estimation methods, the unknown parameter, reliability,
