R-package and code for the paper 'Frequency Domain Statistical Inference for High-Dimensional Time Series'

Repository for PipMet package

The aim of this project involves the analyses the data, removing trends and seasonal effects, identifying the underlying process, understanding the dominant frequencies, and using the residuals to make predictions.

Spectral DEMATEL — diagnose a DEMATEL influence matrix in the browser: structural type, whether it is in scope, and which relationship moves the system most. Runs on WebAssembly, nothing uploaded.

Development version of the TrendLSW R package

App that performs the deconvolution of spectral data into its main components
