摘要：
A note on Helen M. Walker''s The relation of Plana and Bravais to the theory of correlation (Isis 10: 466 484. 1928). Plana had the idea of making 2 variates interrelated by supposing them linear functions of the same variates, but no single symbol of his notation is equivalent to the coefficient of correlation.
