convergenceDFM

convergenceDFM is an R package for convergence analysis in macro-financial panels, combining Dynamic Factor Models (DFM) with mean-reverting Ornstein-Uhlenbeck (OU) processes.

Main Features

• Dynamic Factor Models (DFM): Static and approximate estimation for large panels with VAR/VECM stability checks, Portmanteau tests, and out-of-sample $R^2$.

• Cointegration analysis: Implementation of Johansen's test.

• Ornstein-Uhlenbeck processes: Convergence and half-life estimation based on OU processes.

• Robust inference: HC/HAC sandwich-type estimators via the 'sandwich' package.

• Factor preselection: Methods based on Partial Least Squares (PLS).

• Visualization: Publication-ready graphics.

• Robustness tests: Complete suite of diagnostics and validation.

Installation

From CRAN

install.packages("convergenceDFM")

Development version (GitHub)

# install.packages("devtools")
devtools::install_github("your-username/convergenceDFM")

Optional dependency: cmdstanr

For advanced Bayesian features (optional), install cmdstanr:

install.packages("cmdstanr", 
                 repos = c("https://stan-dev.r-universe.dev", 
                          getOption("repos")))

Note: cmdstanr is not on CRAN and must be installed from the Stan repository. The main functionalities of the package do not require cmdstanr.

Basic Usage

library(convergenceDFM)

# Basic example (adjust according to your main functions)
# data <- prepare_panel_data(your_data)
# dfm_result <- estimate_dfm(data)
# ou_result <- estimate_ou_process(dfm_result)
# plot_convergence(ou_result)
