A comparison Study Between the NadarayaWatson and the Reweighted NadarayaWatson Estimators of the Regression Mean Function
Salha, Raid B. (2015)Nonparametric kernel estimators are widely used in regression estimation. One of the most important kernel estimators of the regression mean function is the NadarayaWatson estimator. Another estimator, which is called ... 
Adaptive Kernel Estimation of the Conditional Quantiles
Salha, Raid B.; El Shekh Ahmed, Hazem I.; Elsayed, Hossam Othman M. (Canadian Center of Science and Education, 20151222)In this paper, we define the adaptive kernel estimation of the conditional distribution function (cdf) for independent and identically distributed (iid) data using varying bandwidth. The bias, variance and the mean squared ... 
Adaptive Kernel Estimation of The Hazard Rate Function
Salha, Raid B. (الجامعة الإسلامية  غزة, 2009)In this paper, we generalized the constant bandwidth kernel estimator of the hazard rate function from Watson and Leadbetter (1964), which depends on a single bandwidth to the adaptive kernel estimator, which depends on ... 
Adaptive Weighted NadarayaWatson Estimation of the Conditional Quantiles by Varying Bandwidth
El Shekh Ahmed, Hazem I.; Salha, Raid B.; Elsayed, Hossam Othman M. (Informa UK Limited, 20150624)In this paper, we define the adaptive Weighted NadarayaWatson estimation (AWNW) of the conditional distribution function (cdf) for independent and identically distributed (iid) data using varying bandwidth. The asymptotic ... 
APPROXIMATING RANDOM DENSITY FUNCTIONS USING WAVELETS
Salha, Raid B. (الجامعة الإسلامية بغزة, 199904)Wavelets are a new family of basis functions that can be used to express and approximate other functions. In this thesis, we investigate the use of wavelets in Probability Theory. This thesis consists of two parts. In ... 
Estimating the Conditional Mode Using the Symmetrized Nearest Neighbor Kernel Estimator
Iqelan, Bisher M.; Salha, Raid B. (الجامعة الإسلامية  غزة, 2015)In this paper, the kernel estimation of the mode of a conditional probability density function is studied. We propose the Symmetrized Nearest Neighbor (SNN) kernel estimator to estimate the conditional mode. We study the ... 
Estimating the density and hazard rate functions using the reciprocal inverse Gaussian kernel
Salha, Raid B. (201306)In this paper, we use the Reciprocal Inverse Gaussian (RIG) kernel to estimate nonparametrically the probability density function (pdf) and the hazard rate function for independent and identically distributed (iid) data. ... 
Hazard rate function estimation using Erlang kernel
Salha, Raid B.; El Shekh Ahmed, Hazem I.; Alhoubi, Iyad M. (Hikari, Ltd., 2014)In this paper, we de ne the Erlang kernel and use it to nonparametically estimation of the probability density function (pdf) and the hazard rate function for inde pendent and identically distributed (iid) data.The bias, ... 
Hazard Rate Function Estimation Using Weibull Kernel
Salha, Raid B.; El Shekh Ahmed, Hazem I.; Alhoubi, Iyad M. (Scientific Research Publishing, Inc,, 2014)In this paper, we define the Weibull kernel and use it to nonparametric estimation of the probability density function (pdf) and the hazard rate function for independent and identically distributed (iid) data. The bias, ... 
Identification Of Periodic Autoregressive MovingAverage Time Series Models With R
El Shekh Ahmed, Hazem I.; Salha, Raid B.; ALAwar, Diab I. (Science Publications, 20140301)Periodic autoregressive moving average PARMA process extend the classical autoregressive moving average ARMA process by allowing the parameters to vary with seasons. Model identification is the identification of a possible ... 
Inverse of invertible standard multicompanion matrices with applications
El Shekh Ahmed, Hazem I.; Salha, Raid B.; ALAwar, Diab I. (Science Publishing Corporation, 20150131)generation of periodic autoregression models to get the desired spectrum and extract the parameters of the model from it when the information of the standard multicompanion matrices is not enough for the extracting of ... 
Kernel Estimation of the Conditional Density Function with Application of the Palestinian Merchandise Imports Data
Alhourani, Sahar Z.; Salha, Raid B. (الجامعة الإسلامية  غزة, 2017)The relationship between a current observation and previous observations, where the conditional density function plays an important role, is the main subject of this paper. To study this relation, the unknown conditional ... 
On Improvement of Hazard Rate Function Estimation Using Adaptive Kernel Estimates
Alhoubi, Iyad M.; El Shekh Ahmed, Hazem I.; Salha, Raid B. (الجامعة الإسلامية  غزة, 2017)In this paper, we use the adaptive kernel estimates method to improve nonparametically the estimator of the probability density function (pdf) using the Erlang kernel (Erlang estimator). In addition, the cumulative ... 
Reweighted NadarayaWatson Estimator of the Regression Mean
Salha, Raid B.; El Shekh Ahmed, Hazem I. (Canadian Center of Science and Education, 20150125)In this paper, the estimation of the regression mean using the Reweighted NadarayaWatson (RNW) estimator has been considered. The RNW is a modification of the NadarayaWatson (NW) estimator in order to obtain some more ...
