Window XP R 2.15 I am running a cluster analysis in which I ask for three clusters (see code below). The analysis nicely tells me what cluster each of the subjects in my input dataset belongs to. I would like two pieces of information (1) for every subject in my input data set, what is the probability of the subject belonging to each of the three cluster (2) given a new subject, someone who was not in my original dataset, how can I determine their cluster assignment? Thanks, John # K-Means Cluster Analysis jclusters <- 3 fit <- kmeans(datascaled, jclusters) # 3 cluster solution and fit$cluster tells me what cluster each observation in my input dataset belongs to (output truncated for brevity): > fit$cluster 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 > 17 . . . . 1 1 1 1 3 1 1 1 1 2 1 2 1 1 1 1 1 . . . . How do I get probability of being in cluster 1, cluster 2, and cluster 3 for a given subject, e.g datascaled[1,]?How do I get the cluster assigment for a new subject?Thanks,John John David Sorkin M.D., Ph.D. Chief, Biostatistics and Informatics University of Maryland School of Medicine Division of Gerontology Baltimore VA Medical Center 10 North Greene Street GRECC (BT/18/GR) Baltimore, MD 21201-1524 (Phone) 410-605-7119 (Fax) 410-605-7913 (Please call phone number above prior to faxing) Confidentiality Statement: This email message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
