I'm trying to use the library mclust for gaussian mixture on a numeric vector. The function Mclust(data,G=3) is working fine but the fitting is not optimal and is using modelNames="E". When I'm trying Mclust(data,G=3,modelName="V") I have the following message: Error in if (Sumry$G > 1) ans[c(orderedNames, "z")] else ans[orderedNames] : argument is of length zero In addition: Warning message: In pickBIC(object[as.character(G), modelNames, drop = FALSE], k = 3) : none of the selected models could be fitted Using variable variance would fit my data better, any idea how to do it?
This list is for issues related to the development of the R language itself. Wouldn't the r-help list be a more appropriate place to ask for assistance? Regards, - Brian
