NettetThe Yeo-Johnson transformation is a flexible transformation that is similiar to Box-Cox, boxcox_trans(), but does not require input values to be greater than zero. ... Yeo, I., & Johnson, R. (2000). A New Family of Power Transformations to Improve Normality or Symmetry. Biometrika, 87(4), 954-959. Nettetwhere Y is assumed to come from a normal distribution. This transformation is continuous in \lambda.Note that this transformation also preserves ordering; that is, if X_1 < X_2 then Y_1 < Y_2.. Box and Cox (1964) proposed choosing the appropriate value of \lambda based on maximizing a likelihood function. See the help file for boxcox for details. Note …
NettetThe Johnson transformation works most of the time but is more complicated. Both attempt to transform data mathematically so the data appear normally distributed. … NettetThomas W. Yee Details The Yeo-Johnson transformation can be thought of as an extension of the Box-Cox transformation. It handles both positive and negative values, …
