This is the original implementation corresponding to the DGP analysis presented in the paper "MHVG2MTS: Multilayer Horizontal Visibility Graphs to Multivariate Time Series Analysis".
- R (>= 3.5.0)
- All data sets can be found in folder data/.
- Data Generating Processes (DGP), the set of 6 linear and nonlinear bivariate time series models
- bwn_models: White Noise models, the independent and correlated bivariate time series processes
- var_models: VAR(1) models, the weak and strong bivariate autoregressive processes
- garch_models: GARCH(1,1) models, the weak and strong generalized autoregressive conditionally heteroscedastic processes
- the GDP are stored in .RData files and are in the following format:
- list of matrix of ts objects, ie. mts, for each DGP
- the csv files contains an instance example of each respective bivariate time series models
- Data Generating Processes (DGP), the set of 6 linear and nonlinear bivariate time series models
- All the measures computed from MHVG's of the DGP's can be found in frolder results/.
- DegreeSeq, the intra/inter/all-layer degree sequences and the ratio degree sequences
- DegreeDistribution, the intra/inter/all-layer degree distributions and respective the mean's and sd's degree distributions
- GlobalFeatures, the intra/inter/all-layer global feature vectors (average degree, average path length, number of communities and modularity) and the relational feature vectors (average ratio degree and intra/inter/all-layer Jensen–Shannon divergense)
- All the empirical results also can be found in frolder results/.
- PCA_results, the intra/inter/all-layer global features and the relationa features PCA analysis
- Clustering_results, the clustering analysis the global and relations feature vectors
