Hi All, I'm fitting a linear (multiple) regression model with 3 predictors + their interactions.
Can anyone suggest some test in R which can help me know whether I need a non-linear (regression) model or some transformation? I'm mostly concerned about finding a way to know whether I should fit a Non-linear model... Thanks, Kim [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
