Product of spacing estimation of entropy for inverse Weibull distribution under progressive type-II censored data with applications

open access: yesJournal of Taibah University for Science, 2022
This paper seeks to estimate the entropy for the inverse Weibull distribution using progressively Type-II censored data. To reach this objective, the entropy is defined through three entropy measures, namely, Rényi, q-entropy and Shannon entropy, and two

Texture Inpainting Using Covariance in Wavelet Domain

open access: yesJournal of Intelligent Systems, 2013
In this article, the covariance of wavelet transform coefficients is used to obtain a texture inpainted image. The covariance is obtained by the maximum likelihood estimate.

Statistical analysis of four-unit hybrid system for masked data

open access: yes上海师范大学学报. 自然科学版, 2017
The likelihood function of four-unit hybrid system is deduced based on masked data.The maximum likelihood estimates of parameters are proposed for hybrid system composed of four units with constant failure rate and linear failure rate based on masked ...

Maximum Likelihood Estimation of Position in GNSS [PDF]

open access: yesIEEE 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 synchronization parameters of the ...

Parameter Estimation for the Two-Parameter Exponentiated Weibull Distribution Based on Multiply Type-I Censored Data

open access: yesIEEE Access, 2019
Multiple Type-I censoring represents that all the test units are terminated at different times. Hence, it is the general form of Type-I censoring, which is common in life testing experiments due to simplicity.

The Effects of Data Imputation on Covariance and Inverse Covariance Matrix Estimation

open access: yesIEEE Access
Various data analysis techniques and procedures (correlation heatmap, linear discriminant analysis, quadratic discriminant analysis) rely on the estimation of the covariance matrix or its inverse (the precision matrix).

Statistical analysis of parallel system for masked data under successive censored life test

open access: yes上海师范大学学报. 自然科学版, 2016
Supposing that the system is composed of two units in parallel and the lifetime of units have constant failure rate and linear failure rate through the origin, we propose maximum likelihood estimate of parallel system for masked data under simple ...

Likelihood decision functions [PDF]

open access: yes, 2012
In both classical and Bayesian approaches, statistical inference is unified and generalized by the corresponding decision theory. This is not the case for the likelihood approach to statistical inference, in spite of the manifest success of the ...

STATISTICAL INFERENCE FOR M/M/1/N QUEUEING SYSTEM WITH BALKING, RENEGING AND REFLECTING BARRIER UNDER QUALITY CONTROL PROCESS [PDF]

open access: yesDelta Journal of Science, 2019
In this paper we develop the confidence intervals for estimatingthe expected value of the units in the system and the maximumlikelihood estimates of the parameters are derived for truncated single -channel Markovian queue with balking, reneging and ...

Research on Maximum Likelihood b Value and Confidence Limits Estimation in Doubly Truncated Apparent Frequency–Amplitude Distribution in Rock Acoustic Emission Tests

open access: yesMathematics, 2022
The b value deduced from the Gutenberg–Richter law is an important parameter for sequence and precursory analyses, both in laboratory acoustic emission tests and seismology.
