Dear All(adsbygoogle = window.adsbygoogle || []).push({});

I need to generate data for my research. Let I have a linear equation with 3 independent variables and 1 dependent variable

a0x0 + a1x1 + a3x3 = y

I want each of my variable(x0, x1, x2) has a defined R2 (r square) with y. Let x0-y = 0.8, x1-y = 0.9, x2-y = 0.85. Any reference how to do this? Thank you.
