NPDE Calculation

Dear Nmusers, I have two questions regarding to the calculation of NPDE and the corresponding package in R. 1) In Cholesky decompsition, should I calculate pd for each observation separately using corresponding mean and sd, or I should use the var-cov matrix and calculate pd for all the observations simultaneously? Should I consider the covariance between different observations here? 2) How can I save the individual NPDE value from the autonpde function in R ?
