estimateECDF {MethylIT} | R Documentation |
This function is used to reduce the number of points used to build a ecdf of an experimental variable. When a variable has a very high amount of experimental values (several millions) could be computationally time consuming to perform a good-of-fit test and a non-linear regression estimation for a theoretical CDF based in such a big number of values.
estimateECDF(x, npoints = 10)

npoints |
minimum number of non-missing values |
The histogram cell midpoints values are used to build estimateECDF.
