lodi is a R package that implements censored likelihood
multiple imputation (CLMI) for single pollutant models with exposure
biomarkers below their respective detection limits. lodi
also contains implementations for standard methods such as single
imputation with a constant and complete-case analysis, although those
methods are primarily designed for comparison with
clmi.
lodi requires rlang >= 0.3.0 to be
installed, so you may want to install or update rlang
before installing lodi.
The package can be installed from CRAN
install.packages("lodi")Or from Github
# install.packages("devtools")
devtools::install_github("umich-cphds/lodi", build_opts = c())The Github version may contain bug fixes not yet present on CRAN, so if you are experiencing issues, you may want to try the Github version of the package.
Once lodi is installed, you can load up R and type
vignete("lodi")to learn how to use the method.
If you encounter a bug, please open an issue on the Issues tab on Github or send us an email.
