WebIn this case, the R 2 value would be: R 2 = 1 − S S r e s S S t o t ( 1). In the meantime, this would be equal to the square value of the correlation coefficient, R 2 = ( Correlation Coefficient) 2 ( 2). Now if I swap the two: a 2 is the actual data, and a 1 is the model prediction. From equation ( 2), because correlation coefficient does not ... WebThe correlation coefficient r is directly related to the coefficient of determination r2 in the obvious way. If r2 is represented in decimal form, e.g. 0.39 or 0.87, then all we have to do to obtain r is to take the square root of r2: The sign of r depends on the sign of the estimated slope coefficient b1: If b1 is negative, then r takes a ... black pineapple company limited jewelry
