Dear All, Some simple interpretation assistance. I am producing regression trees, based on a set of 10 continuous predictors. Have cross validated to fit the model to minimum deviance, prior to summary output. I have not found a source that clearly states the meaning of the residual mean deviance. Some clarification would be greatly apprecieated. I am looking for a value that gives me an idea of the goodness of fit. Thankyou in advance Tom -- ______________________________ Tom Brewer Honours Student Centre of Marine Science Univ. of Queensland Mob: 0433 976 561 _ [[alternative HTML version deleted]]
