Package: VARcheck Type: Package Title: Visual Diagnostic Checks for Vector Autoregressive Models Version: 0.1.0 Authors@R: c( person( "Björn S.", "Siepe", email = "bjoernsiepe+software@gmail.com", role = c("aut", "cre", "cph"), comment = c(ORCID = "0000-0002-9558-4648") ), person( "Jonas M. B.", "Haslbeck", email = "jonashaslbeck@protonmail.com", role = c("aut"), comment = c(ORCID = "0000-0001-9096-7837") ) ) Description: Provides model-agnostic visual diagnostics for vector autoregressive (VAR) models. Given empirical data, model predictions, residuals, and optionally simulated data, the package assembles a multi-panel diagnostic grid: empirical vs. predicted time series, residual inspection, residuals vs. predictions scatter, and posterior predictive style checks via simulated trajectories. Output is a 'patchwork' object composed of 'ggplot2' plots, allowing further customisation via standard 'ggplot2' theme calls. Follows the approach described in Haslbeck et al. (2026) .
