QVFitter.calc_statistics()[Quellcode]

Convert the heavy outputs in the different trials into mean and error for plotting.

Here we assume the error is due to a binomial distribution. Error (standard deviation) for binomial distribution is sqrt(np(1-p)), where n is the number of trials (self._ntrials) and p is the success probability (self._ydata[0][depthidx]/self._ntrials).
