Beta Kernel Estimator for a Cumulative Distribution Function with Bounded Support [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2023
Kernel estimation of the cumulative distribution function (CDF), when the support of the data is bounded, suffers from bias at the boundaries. To solve this problem, we introduce a new estimator for the CDF with support (0,1) based on the beta kernel ...

PCA-kernel estimation [PDF]

open access: yesStatistics & Risk Modeling, 2012
Abstract Many statistical estimation techniques for high-dimensional or functional data are based on a preliminary dimension reduction step, which consists in projecting the sample X 1,...,X n onto the first D eigenvectors of the Principal Component Analysis ...

Comparing nonparametric density estimators using different canonical kernel functions [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2010
In this article we make a comparison between three different nonparametric density estimators .The first estimator is called fixed kernel which uses a fixed bandwidth.

Using Kernel Estimator and K-Mean Clustering Approach to Hand Gesture Recognition [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2013
In this paper we used non parametric density estimator (Kernel Estimator) to estimate probability density function for Image data of Hand Gesture and warping Hand Gesture and we see the curve for Kernel Estimator and combine the curve between Kernel ...

Kernel Minimum Error Entropy Based Estimator for MIMO Radar in Non-Gaussian Clutter

open access: yesIEEE Access, 2021
In this paper, a kernel minimum error entropy (KMEE) based estimator is proposed for the estimation of multiple targets’ direction of departure (DOD), the direction of arrival (DOA), and the Doppler shift with multiple input multiple output radar ...

A New Kernel Estimator of Copulas Based on Beta Quantile Transformations

open access: yesMathematics, 2021
A copula is a multivariate cumulative distribution function with marginal distributions Uniform(0,1). For this reason, a classical kernel estimator does not work and this estimator needs to be corrected at boundaries, which increases the difficulty of ...

COMPARING GAUSSIAN AND EPANECHNIKOV KERNEL OF NONPARAMETRIC REGRESSION IN FORECASTING ISSI (INDONESIA SHARIA STOCK INDEX)

open access: yesBarekeng, 2022
ISSI reflects the movement of sharia stock prices as a whole. It is necessary to forecast the share price to help investors determine whether the shares should be sold, bought, or retained. This study aims to predict the value of ISSI using nonparametric

Nonparametric estimation of the measure of functional dependence

open access: yesAIMS Mathematics, 2021
In this paper, we propose a beta kernel estimator to measure functional dependence (MFD). The MFD not only can measure the strength of linear or monotonic relationships, but it is also suitable for more complicated functional dependence.

Robust kernel density estimation [PDF]

open access: yes2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
We propose a method for nonparametric density estimation that exhibits robustness to contamination of the training sample. This method achieves robustness by combining a traditional kernel density estimator (KDE) with ideas from classical $M$-estimation.
