High-Performance Vector Autoregressions and Local Projections in R

Welcome to the website of tidyMacro!

tidyMacro is an R package for fast estimation and identification of Structural Vector Autoregressions (VAR) and local projections via C++ (Rcpp/RcppArmadillo).

Functionality

  • Fast VAR & VARX reduced form estimations
  • Local projections estimations with clean syntax, support for macros
  • Zero dependency on other packages. Ground up written in C++. All visualizations made with ggplot2 in R.
  • Publication-ready plots out of the box. Each plot is a ggplot2 object, can be ex post customized
  • The package comes with a proper theme
  • Parallel bootstrap computations via OpenMP for maximum speed.
  • Excellent documentation with detailed examples for every function
  • Import data via tidyverse, clean, modify and then supply your final data piping as matrix for Armadillo calculations
  • Example data sets for each replication via already transformed data
