Toolbox for constructing the best histograms  

These tools provide the best histogram, kernel density estimation, Bayesian estimator, and Hidden Markov model, for a given series of event times. Paste or upload the event times, listed in order of increasing time, separated by a comma or a space. Your data will not leave your computer, because the computation is carried out on your computer. Matlab, Python, and R codes are also available for download below. The theory applied here for the purpose of optimizing the estimators can be found in the references.
