This paper reviews the main available software programs to that aim, and focuses on a detailed presentation of VRA, a free access software whay is useful for general likke time series analysis. The fast development of computer resources available to the scientist community and the what does a nonlinear function look like on a graph growing bulk of theoretical knowledge about complex dynamics, have allowed many researches to look for non-linear dynamics in data liks evolution linear ARMA models are unable to explain in a satisfactory manner.

This approach arose in natural sciences physics, biology, Although there is not as a defined branch of empirical research as the Time Series Analysis, some attempts of systematising the apparently disperse set of techniques have led to the so called Nonlinear Time Series Noninear NLTSA, hereafter; see Kantz and Schreiber, Nevertheless, and maybe due to such soes disperse characteristic, the methods involved have not been yet incorporated into standard econometric packages, or they have been embodied very partially into more general environments e.

Those methods can be classified according to Gilmore into metric, dynamical, and topological tools. The dynamical approach deals with nonlinesr the way nearby orbits diverge by means of estimating Lyapunov exponents. Topological methods are characterised by the study of alpha male meaning in relationship organisation of the strange attractor, and it includes close returns plots and recurrence plots.

As an dows of dispersion of these methods, very few programs which allow to apply NLTSA techniques are available. Section 4 focuses on VRA, and section 5 concludes. Recurrence Analysis. As Gilmore pointed out, the topological method has important advantages, among others: 1. It is applicable to relatively small data sets, such are typical in economics and finance; 2.

It is robust against noise. Recurrence analysis is a graphical method designed to locate hidden recurring patterns, nonstationarity and structural changes, introduced in Eckmann et al. The x of embedding vectors recreates the original dynamics only if parameters m and d are properly chosen by using methods like false nearest neighbours for m and mutual information for d. Next, distances not necessarily Euclidean are computed between all of pairs of vectors; recurrence plot relates each distance to a colour e.

Thus, it is a solid rectangular plot consisting of likf whose colours correspond to the magnitude of data values in a two-dimensional array and whose coordinates correspond to the locations of the data values in the array. On the other hand, if the series is white noise, then the recurrence plot should not present any structure at all. Both what is the yellow star on bumble have been attained using RATS graphics; computations were performed using programs written by the authors in Ox 2.

Figure 1. Recurrence plot from Rossler series Figure 2. Such set, however, might not be so clear e. In addition, Webber and Zbilut introduce the concept of cross recurrence plot by which the dynamical behaviour of two time series is compared. Recurrence analysis tools. All the free programs cited at the introduction allow to apply recurrence analysis, though not all of them allow to apply recurrence quantification analysis: that is the case of TISEAN and NDT. VRA and NDT work under Windows, and they are the same main thing: very easy to use general non-linear analysis programs; however, the set of procedures is smaller than TISEAN, and more importantly, they do not allow to vary all control parameters of the different techniques involved.

On the other hand, RQA, exclusively designed to apply nonlinezr quantification analysis, is a set of DOS executables very easy to use,: in this case, control on parameters of the procedures is absolute. As it was shown above, recurrence plots are graphical devices; therefore, software what is the right relationship with god provide suitable high resolution graphical representations, what does a nonlinear function look like on a graph order to be published somewhere.

TISEAN produces a file with the values to voes scattered, depending on the computed distances; thus, the file can be read into a program which enables to attain high quality graphics e. However, it is just able to store the values of one half of the recurrence plot, although it is nnlinear really a serious drawback due to the fact that the representation above and below the main diagonal is symmetric.

RQA output appears on the DOS screen, and it can be hardcopy-captured by any standard screen-dump utility figure 4though variables to be scattered can be stored on separate files, and imported to a graphical program, as TISEAN. NDT allows storing recurrence plots as bitmap extension. Graphical output from NDT Figure 6. Nonlineear that comparison, it stems that VRA is one of the most complete non-commercial non-linear time series analysis software, and one of the easier maybe the easiest of use; that is why we will focus on this program in the next section.

Software comparison. Visual Recurrence Analysis. Then, the program is targeted at empirical researchers on NLTSA, containing a wide range of techniques into two large sets of non standard procedures: 1 the set of quantitative recurrence analysis the main subject of the softwareand 2 the set of non-linear functiion. Both sets are menu-driven in a simple, very easy to learn, way. It fraph free for downloading, use, grah distribution lkke educational or academic research ggraph.

The only difference between this freely available graoh and the commercial one, is the ability of functoin latter of saving prediction values. The free version deos forecasting, but it is not possible to save predictions into a separate file. Installation is quite easy: download the file vra4v2. The version of the program is for Windows 95, 98, and NT, and it needs 5.

The author also recommends a high resolution monitor and the corresponding video card in order to onnlinear all the capabilities of the program. The current version nlnlinear the program is 4. Starting and data manipulation. Next, series must be loaded from an archive, because there is no automatic loading. What does a nonlinear function look like on a graph the format, scalar values must be arranged in a column, and the number of observations is limited to one million, which should be enough for most of the empirical applications what is the difference between market risk premium and equity risk premium economics.

However, data management is quite restrictive: they cannot be segmented no exported, and no transformations are allowed. What does a nonlinear function look like on a graph, users must manipulate data with other packages e. On doee other hand, there is a huge set of interesting trial data files: from a uniform white noise process, to deterministic series like Rossler, Ikeda, Lorenz or Henon. The first recurrence plot.

After loading data, VRA automatically shows a first recurrence plot on the screen, using ahat parameters. Users can choose between 14 colour schemes; in figure 7, ggraph is shown the first recurrence plot of VRA when loading a uniform white noise series in the file Noise. Figure 6. What does a nonlinear function look like on a graph first recurrence ffunction white noise. The time delay embedding. The first recurrence plot that VRA shows can be a beautiful picture, but absolutely uninformative.

It is needed a deep insight into the dynamical structure of the possible multidimensional system that generated the data. To that end, analysts must choose a suitable embedding dimension and whst adequate delay time. To choose the appropriate time delay, users can compute the average mutual information function, as an alternative to the classical autocorrelation function; the latter detects linear correlations, but the former is useful to detect both linear and non-linear correlations.

The time delay should be chosen such that the elements in embedding vectors are no longer correlated, thus subsequent analysis would reveal spatial whah geometrical structures. Next, one can save the resulting graph. Figure 7 shows the procedure applied on the white noise series: the optimal delay corresponds what does a nonlinear function look like on a graph the first minimum in the function, in nonlineaar case, at lag 1 as it was expected.

Figure 7. Then, at the corresponding window, one can choose the minimum embedding dimension an the maximum one along with a parameter which represents a trade-off between speed and accuracyand setting the optimal delay time previously calculated by the mutual information. Figure 8 shows the saved chart for the white noise series: the minimum rate of false nearest neighbours is achieved at an embedding dimension of Figure 8.

The new recurrence plot will be shown. Recurrence quantification analysis. In addition to recurrence plots, VRA implements the recurrence quantification analysis of Zbilut and Webber.
