But these methods do not give good performance results for real time series due to non-linearity and non-stationarity of these data sets. On one hand, most of real world time series data display a time-varying second order structure. On th...

We show, from a topological viewpoint, that most numbers are not normal in strong sense. More precisely, the set of $x \in (0,1]$ with following property is comeager: for all integers $b\ge 2$ and $k\ge 1$, sequence vectors made by frequencies possibile strings length $k$ $b$-adic representation $x$ has maximal subset accumulation points, each them limit subsequence an index nonzero asymptotic ...
