Description

Dynamic Models with Regime-Switching.

Description

Intensive longitudinal data have become increasingly prevalent in various scientific disciplines. Many such data sets are noisy, multivariate, and multi-subject in nature. The change functions may also be continuous, or continuous but interspersed with periods of discontinuities (i.e., showing regime switches). The package 'dynr' (Dynamic Modeling in R) is an R package that implements a set of computationally efficient algorithms for handling a broad class of linear and nonlinear discrete- and continuous-time models with regime-switching properties under the constraint of linear Gaussian measurement functions. The discrete-time models can generally take on the form of a state-space or difference equation model. The continuous-time models are generally expressed as a set of ordinary or stochastic differential equations. All estimation and computations are performed in C, but users are provided with the option to specify the model of interest via a set of simple and easy-to-learn model specification functions in R. Model fitting can be performed using single-subject time series data or multiple-subject longitudinal data. Ou, Hunter, & Chow (2019) <doi:10.32614%2FRJ-2019-012> provided a detailed introduction to the interface and more information on the algorithms.

README

This README file documents the steps necessary to get dynr cooking. That was the first of many food-based puns. It will not be the last.

Who is this repository for?

This repository is primarily for developers. If you're not currently on the development team but would like to be, please contact Sy-Miin Chow at Pennsylvania State University. You will need

Good computer programming skills (R and C preferably)
Decent mathematical ability
Knowledge of or interest in dynamical systems
Some exposure to statistical methods

If you're not a developer and just want to install dynr to run your models, please see the CRAN page including the vignette with installation guidelines.

Contribution guidelines

Writing tests
Code review
Other guidelines

We primarily use a centralized workflow in git. Occasionally, we employ a feature branch style for larger features that may break the master branch for extended periods of time.

Please follow these basic guidelines when writing commit messages.

Separate subject from body with a blank line
Limit the subject line to 50 characters
Capitalize the subject line
Do not end the subject line with a period
Use the imperative mood in the subject line
Wrap the body at 72 characters
Use the body to explain what and why, not how

We use win-builder to help test the repository prior to submitting a new release to CRAN.

A Note to developers: there is a bug in roxygen2 such that the latest version will not build our documentation. It is a known issue that will be resolved soon. In the meantime, use an older version of the package. Install it with devtools::install_version(package = 'roxygen2',version = '5.0.1', repos = c(CRAN = "https://cran.rstudio.com"))

Who do I talk to?

Michael D. Hunter is the Repo owner and admin
Sy-Miin Chow is the principle investigator on the grant that funds dynr
Other members of the development team include but are not limited to Lu Ou, Meng Chen, Linying Ji, Hui-Ju Hung, and Yanling Li
