Question

Calculate rank correlation coefficient of Example 1 in Section 11.4.

Answer 1

`rho=1-(6[SigmaD^(2)+(1)/(12)(m^(3)-m)+(1)/(12)(m^(3)-m)...])/(N(N^(2)-1))`
`=1-(6[4+(1)/(12)(2^(2)-2)+(1)/(12)(2^(3)-2)])/(10(10^(2)-1))`
`=1-(6[4+(1)/(12)(6)+(1)/(12)(6)])/(10xx99)=1-(6(4+0.5+0.5))/(990)`
`=1-(6xx5)/(990)=1-(30)/(990)=1-0.03=0.997`
