Publisher Summary This chapter discusses bivariate distributions, which are populations with two variates. The choice of the method of estimation is quite arbitrary, but in the chapter consideration is only given to the method of least squares. The method of least squares minimizes the sum of squares of the errors. If there are several combinations of the same x and y, then the data is best presented as a two-way contingency table. Rank correlation can be used to give a quick approximation to the product moment correlation coefficient. It is also used when only ranking values can be given.
