Simulation Of Daily Flow Data Using A Stochastic Nonparametric Model (K-Nearest Neighbor)

Szafranski , Bill 1 1 University of Colorado, Boulder Daily flow data for the Usk River in Wales was simulated using a nonparametric bootstrap procedure that captures autocorrelation called k-nearest neighbor (k-NN) (Lall and Sharma, 1996). The objective of the modeling approach was to obtain a lengthy and robust daily...
