ρ = cov ( T , S ) [ cov ( T , T ) cov ( S , S ) ] 1 2 ,
cov ( T , S ) = av ( T S ) - ( av T ) ( av S ) ,
av T = average value of T .
R ( T , S ) = cov ( T , S ) ( av T ) ( av S ) .
ρ = R ( T , S ) [ R ( T , T ) R ( S , S ) ] 1 2 .
R ( T , T ) R ( S , S ) = 1 ,
R ( T , S ) = av ( T S ) ( av T ) ( av S ) - 1.
ϕ ( 0 ) = av ( T S ) ,
ϕ ( ) = ( av T ) ( av S ) ,
R ( T , S ) = ϕ ( 0 ) - ϕ ( ) ϕ ( ) = ρ
av T = fractional part of T which is white ,
cov ( T , T ) = white fractional part × black fractional part of T ,
R ( T , T ) = ratio of black area to white area on T .
ρ = ϕ ( 0 ) - ϕ ( ) ϕ ( ) ,
