First off, that authors really need to stop writing their own comments praising this product. Their lack of English skills and 5 star ratings tend to make their reviews stand out.

The product still doesn't come close to what other statistical products have to offer. It has a nonintuitive interface, no significant documentation and way overpriced for what little it has to offer. Excel offers more, Aabel is even better - and the authors are Korean - who are quite capable of writing a clear, English manual for their product.

I've taught statistics for years - from simple univariant methods to advanced multivariate methods (PCA, PCR, Neural networks and so forth) so I'd like to think I know a bit about available products.

The scary part is that the authors (via their pseudo-reviews) claim that this product is ideal for medical statistics. I sure hope that US MDs aren't using it.

Your money is better spent of a TI-59 calculator.
