Hi all,
Hot on the heels of the release of R 2.15, we are happy to announce the release of Amelia
1.6.1. This update incorporates a few new features and a few bugfixes, including one that
prevented AmeliaView from opening. You can now use the R generic "transform"
function to create new variables in each of the imputed datasets. To learn more, see
section 4.8 of our manual:
http://cran.r-project.org/web/packages/Amelia/vignettes/amelia.pdf
To install this update, run the following lines of code at the R prompt:
install.packages("Amelia", repos = "http://cran.r-project.org")
And here is a list of the changes since the last update to CRAN:
== 1.6.1 (30 Mar 2012) ==
* Fixed a bug that prevented AmeliaView from opening.
== 1.6 (22 Feb 2012) ==
* Added a transform function to create transformed variables
in the imputed datasets.
* Added a mi.meld() function that can combine quantities of
interest using the Rubin rules.
* Added a subset arugment to overimpute.
* write.amelia() can now create a stacked/long imputed
datatset (also updated to AmeliaView)
* Fixed a bug in moPrep (Thanks to Jeff Arnold for the patch)
* missmap() has an arugment to not re-order the variables.
If you have any problems or questions, please feel free to send an email to list.
Cheers,
matt.
