The methods library consists of a set of R packages that can be used to execute observational studies against data in the Common Data Model (CDM) format. The following packages are available:
All OHDSI methods are designed to be able to run customized one-off studies for a particular exposure-outcome pair, but also across a large set of pairs, and using many different predefined analysis choices.
From the OMOP experiment we learned that it is important to measure and understand the operating characteristics of methods in the settings that they're used, and to use these measured operating characteristics to calibrate the estimates produced by the methods. To facilitate these tasks, the following packages have been developed:
Using the OHDSI R packages
All packages have package manuals describing the functions available in the package, and most packages have vignettes that describe how to use the package in a more user-friendly way. You can access the manuals and vignettes from the front pages of each Github repository.
