Hi, I´m having problems trying to compare models obtained using the mixture model fitting function “mix” model1<- mix(data, data.par1,dist="norm") model2<- mix(data, data.par2,dist="norm") anova(model1, model2) When the number of parameters estimated for the two models is different I get an error message: “Error in anova.mix(model1, model2) : binary operation on non-conformable arrays” When both models have the same number of parameters estimated I get a warning saying that the models should be nested: “Warning message: In anova.mix(model1, model2) : The models are not nested” I wonder if anyone can help Thanks in advance Maria -------------------------------------------- Maria Manuel Angélico IPMA, Portuguese Institute for Sea and Atmosphere Lisboa , Portugal tel: ++ 351 213027068 angelico@ipimar.pt [[alternative HTML version deleted]]
