† The indicated variables are calculated but are not shown on the STAT VARS screen.
††
corr is defined for a linear regression only; R
2
is defined for all polynomial
regressions.
Note:
• If
regeq is 4x + 7, then regCoef is {4 7}. To access the “a” coefficient (the 1st element
in the list), use an index such as
regCoef[1].
