Hello,
I am trying to use the powerTransform function in the package car to identify
the lambda: transform my data. However, I receive the following warning:
Warning message:
In estimateTransform(x, y, NULL, ...) :
Convergence failure: return code = 1
I can not find a description of what return code =1 means for the car package.
How do I look that up, or does anyone know what the warning means?
Thank you so much!
Brittany
