Hi, I am looking for a means to compute empirical distribution function for a very large data set and evolution of that edf with time. Here are some specifics. Each day I have an estimate of a distribution function and a new sample of about 1e4 points from the distribution in question. I want to update my estimate to include the new observations (with some aging coefficient to adapt to the changes of the df w/ time). Is there any R (or even non-R) code that can do this? Any relevant references will be appreciated as well. Thanks, Vadim
