To update an installed add-in, quit Excel, find where the add-in is located on your hard drive, right-click on the desired add-in (from the list below), choose "Save Target As" or "Save Link As" (depending on your browser) and save it to where your original add-in was located. Launch Excel and click on the Tools menu to use the add-in (execute Tools: Add-ins if needed to make the add-in available in the Tools menu).

Updates for Excel 2007: traps tracking of more than 256 cells for pre-2007 version and removes restriction on number of cells tracked for 2007 and greater versions; updated message when installed for Excel 2007. Adds Delete Previous MCSim Sheet option; reorganizes the form; adds ability of user to give seed to repolicte results.

|DDV.xla||Updated so that it works with Excel 2010.||10 Jun 2010|
|DDVGN.xla||Enables estimation with more than 32,767 observations. The version on the CD included with the book reports an error when n>32,767. Also improved the way we handle cases of perfect classification. In addition, now includes functions for Logit and Probit NLLS estimation. 4 Oct 2006 revision corrects an error in Logit ML which crept in to the June, 2006 version. 18 Feb 2007 version corrects error in estimation of Robust SEs for NLLS estimation.
