Random walk estimator

Estimation of gaussian random walk

This function performs the estimation of Gaussian random walk through the empirical probability that the samples of multiple sets belong to 1 sigma square root envelope. The determination of standard deviation is estimated applying dichotomy method to the number of samples belonging to a settable square root envelope. The successive results of dichotomy method are displayed until the compliance with the required precision.
