search for: nbclust

Buenos dias, desde hace algunos dias estoy realizando un trabajo,mi computadora es una DELL, windows 10 64 bits, 8G de RAM y disco de estado solido, estoy procesando 29000 filas y 23 columnas, mi codigo es este: nb <- NbClust(datos.scaled, distance = "euclidean", min.nc = 2, #max.nc = 10, method = "complete", index ="all") . y mi error es este: Error: cannot allocate vector of size 2.0 Gb Gracias [[alternative HTML version deleted]]

i m using a package NbClust for cluster analysis. in the following algorithm ->NbClust(m, diss="NULL", distance = "euclidean", min.nc=2, max.nc=15, method = "ward", index = "all", alphaBeale = 0.1) i want to define my own dissimilarity matrix of dimension 38*38. my original data &q...

I am attempting to use NbClust to examine different indices to determine the number of clusters. The code appears to be working and I am getting results. However, I have noticed that each time I run it I may get different answers. For example looking at the DB index one run recommended 6 clusters while the next 5 - the code i...

Dear All,i applied "NbClust", to my data to find optimum number of clusters, and got following resultsNow, i don't know how to read these results. more precisely, i would like to know, how to see which method is more precise for my data considering these index values.your help is needed...thanks in advance Eliza Bott...

I have the same problem you mention here. As there is no answer, did you find the way to obtain the optimal number of groups? Thank you! [[alternative HTML version deleted]]

Dear useRs, i am using NbClust to determine appropriate number of cluster for hclustering. i am consistently getting the following error Error in if (is.na(n) || n > 65536L) stop("size cannot be NA nor exceed 65536") : missing value where TRUE/FALSE needed Does any one know where i am wrong?? thanks in advance...
