Most statistical forecasting methods are based on the assumption that the time series can be rendered approximately stationary (i.e., "stationarized") through the use of mathematical transformations. We also compared our results with the higher ambiguity function-based method.
The methods proposed outperform this method at low signal to noise ratios (SNR) in terms of estimation accuracy and robustness.

$\endgroup$ – Analyst Aug 1 '14 at add a comment |. Graduation thesis performed at shell research center Amsterdam. A time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time.
Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of the Dow Jones Industrial Average. In the literature on dynamic econometrics models, the instability of the form allows us to use GLS for the estimation of time-varying parameters.

Ignoring these factors leads to a wide discrepancy between theory and practice. You can write a book review and share your experiences. Other readers will always be interested in.For modelling time-series data, it is natural to use directed graphical models, which can capture the fact that time ﬂows forward.
Arcs within a time-slice can be directed or undirected, since they model “instantaneous” correlation. If all arcs are directed, both within and between slices, the model is called a dynamic Bayesian network (DBN).
