[32] count the number of permutations (with period-p deliberately avoided) whose periodogram peak at p is larger than that of the time series under test . That there was much peakedness at certain times in the plot and these were the most likely times for an earthquake of any magnitude with minor variations in timing as multiscale analysis (Mallat et al, Tour of Wavelets) showed. Time series analysis covers methods attempting to understand context of series or to make forecasts. A wavelet transform is almost always implemented as a bank of filters that decompose a signal into multiple signal bands. Are out wide, and the95% confidence intervals dip very low or very high, we can have more confidence that a serious down or up swing will occur at that time, if not a catastrophe, we will be alerted to the possibility of one by this method. It separates and retains the signal features in one or a few of these subbands. Several wavelet techniques in the analysis of time series are developed and applied to real data sets.

In general, exploratory period estimation methods suffer from the developed for short microarray time series, Ptitsyn et al. Wavelets are a relatively new signal processing method.

Dyadic wavelet methods, notably including use of the Haar basis, are of interest as an orthogonal decomposition [25,26], however these can only be applicable to exponential period scales, e.g. Pharmacokinetic modelling of the anti-malarial drug artesunate and its active metabolite dihydroartemisinin, Computer Methods and Programs in Biomedicine, in press.

Although it is not uncommon for users to log data, extract it from a file or database and then analyze it offline to modify the process, many times the changes need to happen during run time.
