The Time Series Tools (simts) R package provides a series of tools to simulate, plot, estimate, select and forecast different time series models. Its original purpose was to be a support to the online textbook “Applied Time Series Analysis with R” but can obviously be used for time series analysis in general. More specifically, the package provides tools with the following features:

• Simulation of time series from SARIMA models to various state-space models that can be expressed as latent time series processes.
• Visualization of time series data with user specifications.
• Specific simulation and visualization tools for latent time series models.
• Easy-to-use functions to estimate and infer on the parameters of time series models through different methods (standard and robust).
• Diagnostic and statistical tools to assess goodness of fit and select the best model for the data.
• Estimating and plotting tools to deliver point forecasts and confidence intervals.

To understand the usage of the simts package, please refer to the “Vignettes” tab above.

## Installation

The simts package is available on both CRAN and GitHub. The CRAN version is considered stable while the GitHub version is subject to modifications/updates which may lead to installation problems or broken functions. You can install the stable version of the simts package with:

install.packages("simts")

For users who are interested in having the latest developments, the GitHub version is ideal although more dependencies are required to run a stable version of the package. Most importantly, users must have a (C++) compiler installed on their machine that is compatible with R (e.g. Clang).

# Install dependencies
devtools::install_github("SMAC-Group/simts", build_vignettes = TRUE)
The setup to obtain the development version of simts is platform dependent.
