How can I calculate contribution to R2(%)?
Which Smart PLS correlation data I have to use to calculate contribution to R2(%)?
Would any body kindly help me?
Any assiatnce or guide line will be highly appreciated.

Hi,
If you want to compute the contribution of each independent variable..
Example: y = b1*x1 + b2*x2 +b3*x3
Contribution of x1 = ry1 * b1
Contribution of x2 = ry2 * b2
Contribution of x3 = ry3 * b3
Were:
ry1 = correlation between x1 and y.
b1 = path coefficient
Sum of these contributions = R²
Best regards,
Bido

Re: Calculation of Contribution to R2(%)
This was a nice little bit of calculation that was automatically added to the SPAD- PLS software option.
It is something at even unsophisticated audience members understand
