(12C) Chi Square Statistic

[Joe_H]

Sorry forgot to say the changes in registers I made. R7 in the original had the result but in my program it is R1. Also R4 and R5 are swapped around as R4 can do arithmetic but none was used in the original and a fair bit was with R5. Other registers remain as they were.

So the final result is in R1 (fractional part only).
