Non linear modeling
AFAIK most model fitting techniques will only deal with additive errors, not multiplicative ones. You might want to try fitting: log(y-x) = a*x + e which is linear. Andy
From: Angelo Secchi 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
