Hi RStudio,

I have a question regarding `caret::BoxCoxTrans`

. As you recall this finds the lambda (for highly skewed data) so that a BoxCox transformation can be carried out.

I have a feature/attribute that is highly skewed, skewness = 2.912 and the ratio of maximum value : min value = 208.8. The actual minimum is zero but I found the smallest value that is NOT zero and calculated the ratio. (Correct or not?)

However when I use the `caret::BoxCoxTrans`

to determine the lambda value I get a message stating,

```
[1] 0.004016064 0.009803922 0.000000000 0.052083333 0.010677344 0.030769231

```

Any thoughts?
