First appearance of the statistical paper in which the authors introduced the conceptS of 'Multiple Correlation' and 'Partial Correlation'. "Pearson did not pursue the theory of multiple and partial correlation beyond the point to which he had carried it in his basic memoir on correlation (1896). The general theory of multiple and partial correlation and regression was developed by his mathematical assistant, G. Udny Yule, in two papers published in 1897. Yule was the first to give mathematical expressions for what are now called partial correlation coefficients, whcih he termed "net correlation coefficients." What Pearson had called coefficients of double regression, Yule renamed net regressions" they are now called partial regression coefficients. The expressions "multiple correlation" and "partial correlation" stem from the paper written Alice Lee and read to the Royal Society in 1897."(DSB). …
