Add-on to the R package pcalg for handling missing data
in contrataint-based causal graph discovery. Supports continuous,
discrete and mixed data. Two options are available: 1)
gaussCItwd, disCItwd and
mixedCItwd perform test-wise deletion, where missing
observations are deleted as necessary on a test-by-test basis; 2)
gaussMItest, disMItest and
mixedMItest perform conditional independence tests on
multiply imputed data. Each of these functions can be used as a plug-in
to pcalg::skeleton, pcalg::pc or
pcalg::fci.
Additionally, the package contains all functions required for replicating the analyses in Foraita et al. (2020).
Install the packages graph and RBGL from
Bioconductor. Make sure that rtools is
installed on your computer. Then, simply type in R to install
micd
devtools::install_github("bips-hb/micd")(Note: The latest micd was created using R 4.2.1)
