BOX _COX is an interactive microcomputer program that computes the Box-Cox transformations (Box andCox, 1864; Neter, Wasserman, andKutner, 1888), as well as the sum of squared residuals using these transformations. These transformations may be useful for correcting problems in regression models such as heteroscedasticity of error terms and nonlinearity of the regression function. In addition, such transformations may be useful to equate the mean squared residuals of groups to enable comparison of their respective slopes.
