Hi,
I'm doing some work with linear models, and I've scaled my data using the
scale(dataset) function. This was great at removing the skew, but I now
can't perform the Box Cox transformation on the data set (using the
boxcox(dataset) function), as the scaling has returned negative values.
So my question is: how can I get the scale function to return a positive set
of data (so I can use Box-Cox), or how can I get the boxcox function to
handle negative values.
Many thanks in advance,
Henry
