Web23 de nov. de 2010 · The CDF has a simple non-parametric estimator that needs no choices to be made: the empirical distribution function. It's not quite so simple to estimate a PDF. If you use a histogram you need to choose the bin width and the starting point for the first bin. If you use kernel density estimation you need to choose the kernel shape and bandwidth. small town in new york
