This project focusses on a rigorous statistical method to analyse the results of loss measurements. SAIL uses algorithms from Hidden Semi-Markov Models to estimate the parameters of the real loss process from measurement. It then computes the real loss rate and its variance. SAIL is light-weight and runs in linear time (on the number of samples). You can find the code to perform the analysis, and the data we used in our paper (as well as links to the papers), on the SAIL web page.
