Using the (Iterative) Ensemble Kalman Smoother to Estimate the Time Correlation in Model Error
Tellus: Series A, Dynamic Meteorology and Oceanography, 2023 Numerical weather prediction systems contain model errors related to missing and simplified physical processes, and limited model resolution. While it has been widely recognized that these model errors need to be included in the data assimilation ...

A neutrosophic student’s t –type of statistic for AR (1) random processes [PDF]
Journal of Fuzzy Extension and Applications, 2021 Neutrosophic statistics are used when one is dealing with imprecise and indeterminate data or parameters. In the present paper we propose a method for performing a neutrosophic Student’s t –type of statistical test that concerns the population mean when ...
