The value of \(n(i)\) is the number of sample values \(y\) that are smaller than or equal to \(y_i\). So the first value would be 1/N, the second 2/N etc. The cumulative distribution function (CDF) of the model can be calculated in the same way. First we find the best-fit parameters for a model using kmpfit.
