Hi fellow R-users, I am interested in fitting the following model
yi=log(a+xi*b*e), e~N(0,sigma2) and where x is a known covariate and a and b are parameters to be estimated as is sigma2. I am not sure how to fit such a model using lm or nls. Is there another function I can use to fit this? Thanks for any help.
