Hi at all Members,

Anscombe's quartet, is a very interesting example, but i think that it could be true for value of R-square that are outside the normal range accepted in bioanalytics. If we set the limit of R-square at > 0.98, it's very difficult, or impossible, to meet the situation described by Anscombe; for this limit, the line is well defined with a model that fit very well the data. So, with limit like this, i think that the R-square value could be an helpful parameter, obviously not alone but with the Others.

Best Regards
Roberto
