"Calculation of the Coefficient of determination (R²)"

Can anybody help me

Does squared_correlation means the Coefficient of determination (http://en.wikipedia.org/wiki/Coefficient_of_determination) ?

if not,  how can I calculate this in rapid miner - Coefficient of determination (http://en.wikipedia.org/wiki/Coefficient_of_determination)

Yes Angela. That's exactly what it is. R^2 is the square of the correlation coefficient between Y and Y-hat (the prediction coming out of the regression).
