Support for using glm_weightit() in the outcome model after weighting using weightthem() is added.
New functions as.mimids() and as.wimids() are now available; these take a list of matchit or weightit objects fit to multiply imputed data and transform them into a mimids or wimids object, respectively, for use in balance assessment and to take advantage of MatchThem’s other capabilities.
In this update, the matchthem() function has been enhanced to include support for the quick and cardinality matching methods. These additional methods offer users more options for their matching analyses, catering to a wider range of use cases and data characteristics. Alongside the matching method updates, this release also incorporates improved documentation and inclusion of a newly introduced weighting approach by Nguyen and Stuart, known as averaging probability weights (apw, please see their paper here).
This update is dedicated to enhancing the documentation, providing clearer explanations, examples, and instructions to improve the usability and understanding of the package. The focus is on ensuring that users have comprehensive and detailed documentation to make the most out of the package’s features and functionality.
This update is primarily focused on enhancing the documentation and addressing minor bugs in order to improve the overall performance and user experience of the package. The necessary fixes have been implemented to ensure smoother operation and to address any reported issues.
This update brings significant improvements to the documentation and introduces several new features: 1. The mimira and mimipo objects, which are the output of with() and pool() functions respectively, now inherit from the mice classes mira and mipo. This allows for seamless integration with existing mice methods, 2. When using coxph() with with(), the update ensures that the robust standard errors are correctly applied, 3. A new cluster argument has been added to with.mimids() function. This argument controls whether cluster-robust standard errors should be used to account for pair membership when the model is a svyglm()-type model from the survey package. By default, pair membership is included when present and there are 20 or more unique subclasses (pairs), 4. The cbind() methods have been documented and exported, 5. The mimids and wimids objects have been optimized to reduce their size. They now only contain the supplied mids object and the outputs from matchit() or weightit(), and 6. A new trim() function has been added to trim estimated weights, utilizing WeightIt::trim() with the same syntax (credits go to Nicolas for this contribution).
These updates enhance the functionality, flexibility, and efficiency of the package, providing users with an improved experience.
This update focuses on resolving a few bugs, resulting in improved stability and functionality of the package. The necessary fixes have been implemented to address these issues and enhance the overall performance.
This update includes a modification to the complete() function in order to avoid any potential conflicts with the tidyr package. The updated definition of the complete() function ensures smooth compatibility and eliminates any name clashes that might have occurred.
This update focuses on enhancing documentation and addressing minor bugs, resulting in improved overall performance and user experience.
This update focuses on enhancing documentation and implementing compatibility for robust estimation of standard errors. Specifically, the package now supports compatibility with the svyglm() and svycoxph() functions from the survey package, allowing them to be used as expressions within the with() function. Additionally, new matching and weighting methods have been introduced, such as the full, genetic, and cem matching methods, as well as the ebal and optweight weighting methods.
Furthermore, the package now includes the complete() function, which replaces the previous matchthem.data() and weightthem.data() functions. This new function provides improved functionality and convenience for completing the required data operations within the package.
This update focuses on enhancing the documentation and addressing minor bugs to improve the overall quality of the package. It includes necessary refinements and fixes to ensure a more polished and seamless user experience.
The MatchThem package has been released and can now be accessed on Github and Comprehensive R Archive Network (CRAN).
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
