CORE-Sketch: On Exact Computation of Median Absolute Deviation with Limited Space

Proceedings of the VLDB Endowment, 2023
Median absolute deviation (MAD), the median of the absolute deviations from the median, has been found useful in various applications such as outlier detection.

Enhanced minimum description length CFAR based on median absolute deviation

International Conference on Signal Processing Systems, 2022
The actual radar exposure area contains different types of landforms, resulting in non-uniform radar clutter, which significantly reduces the target detection performance and makes it difficult to maintain a constant false alarm probability.

Approximating Median Absolute Deviation with Bounded Error

Proceedings of the VLDB Endowment, 2021
The median absolute deviation (MAD) is a statistic measuring the variability of a set of quantitative elements. It is known to be more robust to outliers than the standard deviation (SD), and thereby widely used in outlier detection.

Performance of median absolute deviation and some alternatives to median absolute deviation control charts for skewed and heavily tailed process

Quality and Reliability Engineering International, 2021
In this paper, X¯ charts based on robust scale estimators (known as Sn and Qn estimators) are proposed, and the performance of control charts based on median absolute deviation (MAD) is compared with those based on some alternatives to MAD, which do not ...

Improving the robustness of circular curve fitting with equality constraints using the median absolute deviation method

Survey Review
Circular curve fitting with equality constraints using robust nonlinear weighted total least squares with equality constraints (RNWTLSEC) based on the iteratively reweighted method is affected by the initial values.

Bahadur representations for the bootstrap median absolute deviation and the application to projection depth weighted mean

Metrika (Heidelberg), 2018
Median absolute deviation (hereafter MAD) is known as a robust alternative to the ordinary variance. It has been widely utilized to induce robust statistical inferential procedures.
