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
