I have a growth curve, which is essentially an ECDF: Statistically, it's F(x)...> GrowthCurve[1] 0.06919932 0.24154761 0.42206402 0.61412408 0.72228295 0.79727292 0.86605315 0.91271120 0.98258397 1.00000000 I'd like to fit a Weibull Curve (then a LogLogistic) to this ECDF, and have no clue how to go about doing it. I'm relatively new to R (obviously). Thanks!
Fitting curves to an ECDF will result in a fit that has the same precision as the ECDF if variances are calculated correctly. So why not stop with the ECDF as your estimator?
