the purpose of this study is to find the percentiles of fuzzy numbersand to demonstrate their applications, which include finding weightedmeans, dispersion indices, and the percentile intervals of fuzzy numbers. thecrisp approximations of fuzzy numbers introduced in this paper are new andinteresting for the comparison of fuzzy environments, such as a variety of economic,financial, and engineeri...

Robust estimation of a mean vector, topic regarded as obsolete in the traditional robust statistics community, has recently surged machine learning literature last decade. The latest focus is on sub-Gaussian performance and computability estimators non-asymptotic setting. Numerous are computationally intractable, which partly contributes to renewal interest estimation. centrality estimators, ho...

An extensive body of literature has shown that combining forecasts can improve forecast accuracy, and that a simple average of the forecasts (the mean) often does better than more complex combining schemes. The fact that the mean is sensitive to extreme values suggests that deleting such values or reducing their extremity might be worthwhile. We study the performance of two simple robust method...

Hotelling T control chart is one of the most important chart used to statistical quality control in the manufacture processes. However, this chart is sensitive to the non normal data and therefore, must be modified to improve its behavior with this kind of data. In this paper, we propose two new alternatives charts based on change the usual mean and covariance estimator by robust location and s...

OBJECTIVES In sib pair studies, quantitative trait loci (QTL) identification may be adversely affected by non-normality in the phenotypic distribution, particularly when subjects falling in the tails of the distribution bias the trait mean or variance. We evaluated the robustness and power of reducing the influence of subjects with extreme phenotypic values by Winsorizing non-normal distributio...

Water pH and active ingredient concentration are two of the most important variables to consider in the manufacturing process of fungicides. If these variables do not meet the required standards, the quality of the product may be compromised and lead to poor fungicide performance when water is used as the application carrier, which is in most cases. Given the correlation between the variable...

The purpose of this article is to analyze various methods for measuring central tendency in statistics, including arithmetic mean, median, winsorized outlier exclusion method, Hodges-Lehmann estimator, and quantile estimation much more. advantages disadvantages each these are discussed, as well their practical applications performance analysis distributed systems. In particular, we focus on the...
