Frequency Curves and Correlation

Originally published in 1906 by C. & E. Layton, Limited, this work, with its many later improvements, became a standard textbook on curve-fitting and was several times reissued. Reprinted here is the 1953 fourth edition of the book, published by Cambridge University Press, and containing a preface by the author, Sir William Elderton, in which he comments on the changes that he introduced.
