Some Forecasting techniques have been developed using Multiple Signal Classification (MUSIC) and Fourier Techniques to get the most natural trends in the data forecasted to the future. Also to assess exponential trends, a Markov Bayesian Monte Carlo Path Integral was carried out to determine the probability of threshold crossing within a certain time frame.
