Thank you. I was obviously mis-interpreting the AIC results. RdR -- View this message in context: http://r.789695.n4.nabble.com/gamlss-results-for-EXP-and-LNO-seem-to-have-reversed-AIC-scores-tp4413702p4415275.html Sent from the R...
Actually, I think I've spotted it: the link function for sigma is "log" and exp(0.69) is nearly 2 -- the original sigma -RdR -- View this message in context: http://r.789695.n4.nabble.com/low-sigma-in-lognormal...
Hi, I'm a bit puzzled by the gamlss fitting of exponential and lognormal data. Gamlss seems to think that exponentially distributed data fits better with a lognormal distribution, and vice versa. For example, X <- rexp(1000) Gexp <- gamlss(X...
Hi, I'm playing around with gamlss and don't entirely understand the sigma result from an attempted lognormal fit. In the example below, I've created lognormal data with mu=10 and sigma=2. When I try a gamlss...
