This is not an excel macro. It is a really complex algorithm constructed on FORTRAN. Excel is just a rudimentary user-interface; an overall-compatible format to introduce data easily and quickly.

SPSS, SAS, and now TrendingBot are specialized software, and all three are expensive--for the data crunching it purports to do, the cost of 990 Euros is not at all outrageous.

Being a long-ago veteran of SPSS, trending software is analysis software--in our heads most of us struggle with understanding simple trends as soon as a second variable is introduced. Certainly adding a 4-5 variable analysis requires a computational effort, hence programs like this. For example. What was the reason for Obama to only win 53% in last November's election? Was it race? Was it the conservative message of fear? Was it elitism? And how did it change from September through November? Take the data and pull out the variables to test, and do the work.

This GAOTD offering of TrendingBot like many is designed for a niche market. What it does you cannot do with Excel alone, and would do in an hour what would literally take weeks by hand. If you do not have an interest or understanding of this niche, fine, don't comment. I don't comment on the dozens of multi-media tools and screensavers I have no interest in. For those who need it but have not yet been able to invest in the full version or in the equally costly SAS SPSS or other packages (just as obtuse to understand and use), this giveaway may be just the thing.

To the developers,
First, thanks for making the effort, bringing your tool to GAOTD.
Now, to practical matters, your tool is not intuitive to use and the accompanying movie is too fast to be followed and learn from the uses and capabilities of your tool.
Therefore, a help file with step-to-step instructions and examples could be helpful.
Best regards and again, thanks,
Gad

While it does concern me that the website and videos contain almost no information, and a forum link is a poor way to illustrate the features of a product, making the product available here on GOTD does give potential users a way to evaluate it.

As I don't have Excel installed and I haven't done much of this sort of thing since college, I'm not the right person to evaluate this product. However, it's a very crowded field, and this is an expensive product with a very limited focus. I've seen many packages over the years which could analyze data and automatically generate potentially complex mathematical models. You can get zillions of hits via Google, but be aware that analysis and modeling are different things. Here's a link to tons of free statistical software. The list has been kept updated, but many of the descriptions haven't. I tried a number of the links; they were all valid, and much of the software had been kept more-or-less updated.

Sorry about the OpenOffice issue but we are extremelly small and chose the most commonly used and compatibility-problems-free brand (Microsoft)
