- TITLE(boxcoxplot @@ Finding a Transformation)
- USAGE(
- boxcoxplot(data, group, p=seq(-1,2,length=20))
- )
- ARGUMENTS(
- ARG(data @@ a (numeric) vector containing the data.)
- ARG(group @@ an optional vector which specifies the
- grouping of the data.)
- ARG(p @@ a vector containing the powers.)
- )

- LANG(boxcoxplot) draws a plot of the Box-Cox
- profile likelihood for the powers in the vector LANG(p).
- This is used for selecting a power transformation for

- or normalising the data in a one-way ANOVA (if the argument
- LANG(group) is present).
