It can be used for:
1. stochastic signal processing
2. autoregressive model identification
3. matched (inverse) filter design
4. Histogram analysis
5. Calcution of the entropy of a timeseries
6. Non-linear analysis (3rd order statistics)
7. smoothing, prediction, filtering
8. Test for Hurwitz and Unit-Circle Polynomials
9. handles missing values (NaN's)
Several criteria (AIC, BIC, FPE, MDL, SBC, CAT, PHI) for the selection of the order of an autoregressivemodel are included. Furthermore includes the toolbox a fast version ifthe Yule-Walker method for estimating Autoregressive parameters, the AutocovarianceFunction (ACovF), Autocorrelation Function (ACF), Partial ACF (PACF),andsome other useful staff. Demo programs can be started with "demo" or "demotsa". Version 2.40 (and higher) provides fast algorithms for testing polynomials; and many functions (e.g. ACovF and the Levinson-Durbin algorithms) are implemented for multiple series.
Latest Version 4.3.3, 19 Dec 2015. Tested with Matlab 8.x and Octave 3.x
