Warning: If you now calculate 2-Var Stats on your data, the variables a and b (along
with r and r
2
) will be calculated as a linear regression. Do not recalculate 2-Var Stats
after any other regression calculation if you want to preserve your regression
coefficients (a, b, c, d) and r values for your particular problem in the StatVars menu.
