Data for: Enhanced Principal Tensor Analysis as a tool for 3-way geological data reconstructions
Description
The folder PTA_SSA contains 9 files: 1. readme.txt - this file 2. PTA_SSA.R - R script with the function PTA_SSA() 3. PTA_SSA_Example.R - R example script 4-9. tensor_*.txt - text example files with different proxies (columns - time steps (1-st dim), rows - different sites (2-nd dim)) PTA_SSA: Function: PTA_SSA() - calculates Tensor Decomposition of 3-way data tensor (Principal Tensor Analysis merged with Singular Spectrum Analysis): 3-way data tensor is transformed to 4-way data tensor using delay time technique followed by Tensor Decomposition (PTAk package) and SSA reconstruction (Leibovici, 2010; Ghil et al., 2002). PTA_SSA_Example: Example on how to use the PTA_SSA() function. (6 sites, 6 proxies, see the article for details) Language: R Dependencies: PTAk package (Leibovici, 2010) Platform: Cross-Platform License: Open-Source S. Kotov, H.
