The software is a complete package for nonlinear-dynamics time series analysis. By "complete" I mean simply that the only additional things you need to use the software are 1) some data and 2) matlab. The techniques included emphasize nonlinear prediction and surrogate data, as well as my own delta-epsilon technique. Many important techniques are not represented, for instance algorithms for estimating lyapunov exponents. This selection reflects my own research interests and pedagogical style, and is in no way a comment on those missing methods.
