Universal surrogate likelihood functions for nonnegative continuous data

Thu, 23 Apr 2026 05:01:20 GMT

title: Universal surrogate likelihood functions for nonnegative continuous data abstract: 摘要： In independent and identically distributed situations, we show that one can properly correct the Poisson and the negative binomial likelihood functions to become asymptotically identical to the profile likelihood function for the mean parameter of nonnegative continuous distributions under mild conditions. We present theoretical justifications and use data analyses to demonstrate the merit of our new robust likelihood method. 其他題名： Metrika 出版者： Berlin/Heidelberg: Springer Berlin Heidelberg 出版日期： 2015-08-01 出處： Metrika, 2015-08, Vol.78 (6), p.635-646 資源來源： Springer Nature - Complete Springer Journals 版權： Springer-Verlag Berlin Heidelberg 2014 識別號： ISSN: 0026-1335 識別號： EISSN: 1435-926X 識別號： DOI: 10.1007/s00184-014-0519-3

Two-stage signal restoration based on a modified median filter

Thu, 23 Apr 2026 05:01:10 GMT

title: Two-stage signal restoration based on a modified median filter abstract: 摘要： Median filter is a robust technique for signal restoration when outliers occurred within observations. Moreover, smoothing splines is also an alternative method for recovering the underlying signals. Interestingly, we found that neither median filter nor smoothing splines dominates each other. To obtain a more robust signal estimate, a two-stage procedure for signal denoising is considered, in which the smoothing spline method is applied again to capture possible information within the differences of median filter and smoothing spline estimates. Then, according to an approximate estimator of -risk, a modified median filter method is proposed to estimate the underlying signals. Various comparisons are made via simulation studies to illustrate the superiority of the proposed method. 出版者： Abingdon: Taylor & Francis 出版日期： 2016-01-02 出處： Journal of statistical computation and simulation, 2016-01, Vol.86 (1), p.122-134 版權： 2015 Taylor & Francis 2015 版權： Copyright Taylor & Francis Ltd. 2016 識別號： ISSN: 0094-9655 識別號： EISSN: 1563-5163 識別號： DOI: 10.1080/00949655.2014.996152
