    Time series analysis has become a hot topic with the rise of quantitative finance and automated trading of securities. The base distribution of R includes a time series class called ts. We don't recommend this representation for general use because the implementation itself is too limited and restrictive.A time series with additive trend, seasonal, and irregular components can be decomposed using the stl() function. Note that a series with multiplicative effects can often by transformed into series with additive effects through a log transformation (i.e., newts <- log(myts)).

Feb 04, 2013 · Our time series model consists of a set of blocks partitioning the observations. All model parameters are constant within each block but undergo discrete jumps at the change points (Section 2.5) marking the edges of the blocks. The model is visualized by plotting rectangles spanning the intervals covered by the blocks, each with height equal to ... time series microarray data, the use of dynamic Bayesian networks (DBNs) is a promising alternative, since DBNs can treat time delay information and can construct cyclic networks.
