// // Amelia II - User visible changes // // // == 1.2-14 (16 Nov 2009) == * Fixed a bug that "ords" variables would return multiple copies of the same level. == 1.2-13 (09 Aug 2009) == * Fixed a small bug in the error checking routines that handled nominal variables. == 1.2-12 (11 Jul 2009) == * Fixed a bug in AmeliaView that caused it to crash. == 1.2-11 (10 Jul 2009) == * Minor bugfixes in removing test code from AmeliaView() and handling of the priors. == 1.2-10 (07 Jul 2009) == * Fixed a bug in the error checking routine that occurred when users put all of their variables into one of (idvars, noms, ords, ts, cs). == 1.2-9 (02 Jul 2009) == * Fixed typos in the manual with regard to ridge priors and clarified the advice about them. === 1.2-8 (01 Jul 2009) == * Major update to the Amelia manual (now compiled as a vignette using Sweave). * Changed a typo that stated values were the "percent missing" when they should have been "fraction missing." This is fixed. === 1.2-7 (29 Jul 2009) == * In the amelia output, mu and covMatrices now have relevant dimension names to be able to tell which column which. * Fixed a bug in the handling of priors that may have affected answers, but not significantly. * The missmap() function can now accept any matrix or data.frame, not just Amelia output. This allows for drawing a missingness map before running amelia(). == 1.2-0 (09 Apr 2009) == * Amelia output is now an instance of the S3 class 'amelia'. * Imputations are now stored in a list of length 'm' (the number of imputations) in output$imputations, which is of the class 'mi', making it simple to pass to Zelig. * Amelia output contains a matrix of means (one column for each imputation) and an array of covariance matrices. These are the posterior modes found by the EM algorithm in each imputation.
