Solution: r12 = 0.8 r23 = 0.9 r13 = 0.82 r23.1 = ? R1.23 = ? We know (r_{23.1} = frac{r_{23} - r_{12} times r_{13}}{ sqrt{ (1-r_{12}^2) (1-r_{23}^2) } }) (= frac{0.9 - 0.8 times 0.82}{ sqrt{ (1-0.8^2) (1-0.9^2) } }) = 0.933 (R_{1.23} = sqrt{frac{ r_{12}^2 + r_{13}^2 - 2 times r_{12} times r_{23} times r_{13} }{ 1 - r_{23}^2 }}) ( = sqrt{frac{ 0.8^2 + 0.82^2 - 2 times 0.8 times 0.9 times 0.82 }{ 1 - 0.82^2 }}) = 0.634
