Calculators:
fx-991es plus
Posted 08 December 2010 - 11:04 PM
I just bought my new calculator (fx-991es plus) but I'm having trouble finding "r" in STAT mode (the product moment correlation coefficient). Usually its in SHIFT-1 menu then 7th option ("reg"), but my calculator only goes up to 3 in this menu, the other 4 menu options are missing! Any idea where they are?
