// // Amelia II - User visible changes // // // == 1.7.6 (24 Nov 2019) == * Added "x.las" and "gap.xaxis" arguments to missmap() to allow for more control over the axis. * Added xlim/ylim arguments to disperse() * Moved documentation to roxygen * Fixed bug in compare.density() when only 1 missing value. * Minor bug fixes == 1.7.5 (07 May 2018) == * Fixed bug with factor names under perfect collinearity * Added "draws" argument to overimp to control number of overimputation draws * Fix issue with tibbles and tscsPlot() * Fix issues with missmap() * Fixed issue with iterHist indicators being reversed == 1.7.4 (21 Nov 2015) == * Fixed issue with log axes in overimpute * Allow for vector in 'main' argument in tscsPlot() * Moved a collinearity check from error to warning. * Handle subsets better in moPrep() * tscsPlot() won't throw an error when cs is unspecified and plotall=TRUE * Fixed other small bugs and issues == 1.7.3 (14 Nov 2014) == * Fixed bug with overimp not being respected * Added an argument boot.type='none' to amelia() to allow it to run on the original, non-bootstrapped data * Fixed bug in plot.amelia() with matrix inputs * Fixed bug with lower bounds not being respected * Made compatible with most recent versions of Rcpp and RcppArmadillo == 1.7.2 (08 Jun 2013) == * Bug fixes to priors (especially important for multiple overimputation). * Fixed issue with names of imputations for integration with Zelig. == 1.7.1 (24 Mar 2013) == * Speed improvement (thanks to Paul Johnson). * Amelia now requires R>=2.13.5 * missmap() now displays correctly when data is completely observed. * An error is now called when users try to use overimpute() on a variable marked as nominal. * Fixed a bug when all imputations resulted in uninvertible covariance matrices. * Fixed a bug where incorrectly setting the emburn argument could cause a segfault. * Various package cleanups for CRAN compatibility. == 1.7 (10 Feb 2013) == * Ported core EM algorithm to C++. Speed should increase. * Plots in AmeliaView should now use Quartz on Mac OS X instead of X11. * Amelia now requires R >=2.14.0. * Amelia now can run its imputations in parallel using infrastructure from R's parallel package. Note that R < 2.15.3 will crash if parallel is used while tcltk is loaded (or has been loaded and then unloaded). This will be fixed in R 2.15.3 (the patched version of 2.15.2) and we will require R>=2.15.3 when that version is released. * Fixed bug with priors not working correctly. * Fixed bug with character variables set to nominal. == 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. == 1.5-4 == * Fixed a bug with error messages. == 1.5-3 == * Fixed a bug with completely missing rows in the tscsPlot(). == 1.5-2 (26 Apr 2011) == * Fixed a bug in the handling of priors. == 1.5-1 (23 Nov 2010) == * Fixed a bug in the new GUI where it didn't respect the "intercs" option. == 1.5-0 (23 Nov 2010) == * Major changes to the AmeliaView GUI. == 1.2-18 (4 Nov 2010) == * Fixed a bug when all variables are set to nominal or ordinal. == 1.2-17 (10 May 2010) == * Fixed a bug with the 'ask' argument when using "plot" on an 'amelia' object. == 1.2-16 (20 Mar 2010) == * Fixed a bug when priors specified. * When priors are used, Amelia now tries to use starting values with the prior-filled data. == 1.2-15 (20 Feb 2010) == * Fixed a bug when only 1 variable is not an ID variable or a nominal/ordinal variable. * Fixed a bug with the naming of columns in the imputation process. == 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.
