Abstract We present a new approach on shape preserving estimation of probability distribution and density functions using wavelet methodology for multivariate dependent data. Our estimators preserve shape constraints such as monotonicity, positivity and integration to one, and allow for low spatial regularity of the underlying functions. As important application, we discuss conditional quantile estimation for nancial time series data. We show that our methodology can be easily implemented with B-splines, and performs well in a nite sample situation, through Monte Carlo simulations.
