avar
package This package provides the tools necessary to compute the empirical Allan Variance (AV) and use it to estimate the parameters of (latent) time series models. The estimation of the Allan Variance is performed through the estimator proposed by Allan (1966) and, based on this quantity, the Allan Variance Linear Regression (AVLR) approach (or Allan Variance Slope Method) is often used by engineers to retrieve the parameters of time series models which are assumed to underlie the observed signals (see for example Guerrier, Molinari, and Stebler 2016). These estimators are implemented in this package along with the relevant plotting and summary functions.
The avar
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 avar
package
with:
install.packages("avar")
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). Once you’ve made
sure that you have a compatible C++ compiler installed on your computer,
run the following code in an R session and you will be ready to use the
devlopment version of avar
.
# Install dependencies
install.packages(c("devtools"))
# Install/Update the package from GitHub
devtools::install_github("SMAC-Group/avar")
# Install the package with Vignettes/User Guides
devtools::install_github("SMAC-Group/avar", build_vignettes = TRUE)
