Package: SVARtca Type: Package Title: Transmission Channel Analysis in Structural VAR Models Version: 1.0.3 Date: 2026-09-30 Authors@R: c( person("Muhammad", "Alkhalaf", role = c("aut", "cre"), email = "muhammedalkhalaf@gmail.com", comment = c(ORCID = "0009-0002-2677-9246")), person("Enrico", "Wegner", role = "ctb", comment = "Author of the MATLAB TCA toolbox the package is ported from; co-author of the original methodology"), person("Lenard", "Lieb", role = "ctb", comment = "Original methodology"), person("Stephan", "Smeekes", role = "ctb", comment = "Original methodology"), person("Ines", "Wilms", role = "ctb", comment = "Original methodology")) Description: Implements Transmission Channel Analysis (TCA) for structural vector autoregressive (SVAR) models following the methodology of Wegner, Lieb, Smeekes and Wilms (2025) . TCA decomposes impulse response functions (IRFs) into contributions from distinct transmission channels using a systems form representation and directed acyclic graph (DAG) path analysis. Supports overlapping channels, exhaustive 3-way and 4-way decompositions via inclusion-exclusion principle. This is a parallel R implementation of the 'tca-matlab-toolbox' ().
