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
