(12C) Chi Square Statistic

[Joe_H]

Thanks SlideRule that's a very interesting source of information that I will explore.

As it is for business applications the accuracy of the probability value is ok to only 2 decimal places I reckon so I'll see where it can be reduced to as simple a formula that meets that requirement. What he has in that paper may work. He's talking about accuracy to e-07 etc. I think that is unnecessary if space savings can be made with a cruder estimate.

I'll come back on this.
