I find the regression application for the HP 19B II really easy to use and helpful, enabling me to do forecasting for exponential, power and logarithmic curves as well as linear. It returns the formulas for these curves. Howver, I do find the process slow and cumbersome. I don't think the standard MS Excel offers what I'm talking about so I'm looking for a reasonably priced stat pac that will do this that works as an Excel Addin. Has anybody had any experience with exactly what I'm talking about here? I've researched several packages on the Inet but none of them actually address the applications I need. It wouldn't necessarily have to be an Excel Addin but I think it would be easier to work with. Thanks.
