      Adaptive Kernel Estimation of the Conditional Quantiles

      Salha, Raid B.; El Shekh Ahmed, Hazem I.; El-sayed, Hossam Othman M. (Canadian Center of Science and Education, 2015-12-22)
      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 Weighted Nadaraya-Watson Estimation of the Conditional Quantiles by Varying Bandwidth

      El Shekh Ahmed, Hazem I.; Salha, Raid B.; El-sayed, Hossam Othman M. (Informa UK Limited, 2015-06-24)
      In this paper, we define the adaptive Weighted Nadaraya-Watson estimation (AWNW) of the conditional distribution function (cdf) for independent and identically distributed (iid) data using varying bandwidth. The asymptotic ...

      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 Moving-Average Time Series Models With R

      El Shekh Ahmed, Hazem I.; Salha, Raid B.; AL-Awar, Diab I. (Science Publications, 2014-03-01)
      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 ...

      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 Nadaraya-Watson Estimator of the Regression Mean

      Salha, Raid B.; El Shekh Ahmed, Hazem I. (Canadian Center of Science and Education, 2015-01-25)
      In this paper, the estimation of the regression mean using the Reweighted Nadaraya-Watson (RNW) estimator has been considered. The RNW is a modification of the Nadaraya-Watson (NW) estimator in order to obtain some more ...
