I initially tested your Excel Add In using MS Office 2007.
I could not find out how your Regression product could be uploaded into Excel 20007 as an addin. How do you load it?
Also the "Actual vs Predicted " cart would not work after the first use of your regression product. It is obvious, that there are some bugs in your program realtive to Office 2007 SP1.
Please let me know how I can get your program functioning as advertised.
The product has been tested in Excel 2007. It is not an add-in but a template.
The Actual vs Predicted chart behavoiur may have something to do with your input data. Please feel free to send your template through by relying to the confirmation message of this post so that we can investigate.
