It's not an error, it's only a warning, at least to the level of my

It suggests you managed to send negative or infinite numbers to
dweibull, a distribution which only supports values when given
positive, finite numbers. Look at your data more closely.
And learn to post in plain text. HTML does a poor job of communication.
