Data for: Enhanced Principal Tensor Analysis as a tool for 3-way geological data reconstructions

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
