Abstract:This paper deals with the L p -consistency of wavelet estimators for a density function based on size-biased random samples. More precisely, we firstly show the L p -consistency of wavelet estimators for independent and identically distributed random vectors in R d . Then a similar result is obtained for negatively associated samples under the additional assumptions d = 1 and the monotonicity of the weight function.
Keywords:Wavelet estimator  consistency  size-biased sample  negatively associated  approximation
