摘要
One hundred years ago Karl Pearson derived an approximate formula for the correlation between ratios with a common divisor and cautioned to be wary of correlating ratios. The exact formula for the correlation between ratios is derived. It can provide a better reference point of no connection when correlating ratios with a common divisor. (C) 1999 Elsevier Science B.V.
