In this paper, we introduce a wavelet-based method for estimating the EDR space in Li's semiparametric regression model achieving dimension reduction. This is obtained by using linear wavelet estimators of density and functions that are involved covariance matrix conditional expectation whose spectral analysis gives directions. Then, consistency proposed proved. A simulation study allow one to ...

background: chronic kidney disease is asymptomatic until its last stages and though it is increasing globally, we are faced with paucity of a population-based model to assess this disease, particularly in developing countries. therefore, the aim of this study was to estimate the prevalence and trends of ckd according to a new estimation method.   methods: using multiplier method, we estimated t...
