Hi, is there a way in R to fit a non linear model like y=x+exp(a*x)*eps
where a is the parameter and eps is the error term? Thanks Angelo ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
