Hi, I'm new to R and am hoping someone might be able to help with the following lme problem. I am trying to fit an ellipse equation to some spatial human factors data, varying the major and minor axes randomly and specifying an exp~ variogram for errors. Using normally-distributed random effects produces some -ve minor/major axes. I am hoping to be able to specify a gamma distribution to overcome this, but have not been able to work out how. Does anybody know an R function that implements lme with gamma-distributed random effects? Any help or advice would be greatly appreciated! Thanks
