Hi, I have used the algoritm HINov (Heuristic Identification of Noisy Variables) and I have a problem with a dataset. Indeed there is always the error: "Error in kmeans(y, y[initial.Centers(y, u), ]) : initial centers are not distinct" I send my data set (Spss file): the variables are quantitative. The HINoV's instructions are: library(clusterSim) x<-data.frame(palmitic, p_eic, stearic, oleic,linoleic,l_eic, arachidic, eicosenoic) r1<- HINoV.Mod(x, type="metric", s=1, 4, method="kmeans",Index="cRAND") If I delete the variable l_eic, I won't have the problem: why is it?. Best regards. Alex
