similar to: hierarchical clustering with Jaccard index

I am doing hierarchical clustering with cluster package.  I couldnot find similarity measures like matching coefficient, Jaccard coefficient and sokal and sneath. Could anyone please tell package with similarity measures for binary data? kind regards, Ms.Karunambigai M PhD Scholar Dept. of Biostatistics NIMHANS Bangalore India From cricket scores to your friends.

Dear R-help, I am doing clustering via finite mixture model. Please suggest some packages in R to find clusters via finite mixture model with continuous variables. And also I wish to verify the distributional properties of the mixture distributions by fitting the model with lognormal, gamma, exponentials etc,. Thanks in advance,  warm regards,Ms.Karunambigai M PhD Scholar Dept. of Biostatistics

hi r-help, i am doing kmeans clustering in stats. i tried for five clusters clustering using: kcl1 <- kmeans(as1[,c("contlife","somlife","agglife","sexlife",                         "rellife","hordlife","doutlife","symtlife","washlife",                       

hi, I am trying to calculate distance matrices for binary data frame. I am using dist.binary in 'ade4' package. This is the code i run and get error message as 'missing value where True/False needed: clss <- as.data.frame(cls) dist.binary(clss, method = 1, diag = FALSE, upper = FALSE) Also, if i convert the factors into numeric(i.e,1&2 in the place of 0&1 for present/absent

hi all, I am doing hierarchical clustering using similarity measures for binary data using package ade4 and hclust function. For method=8 and method = 9 of dist.binary, I am getting Na values. Hence, hclust function is giving error as Error in hclust(d8, method = "ward") :   NA/NaN/Inf in foreign function call (arg 11). I think the fact that due to zero in the denominator of the

Dear R-help, Can anybody tell me which R package has Lo-Mendell Rubin LR test and Bootstrap LR test to compare the model fit between k class and k+1 class model for Latent class analysis?

Hi I have a large dataset, containing a wide range of binary variables. I would like first of all to compute a jaccard matrix, then do a PCA on this matrix, so that I finally can do a hierarchical clustering on the principal components. My problem is, that I don't know how to compute the jaccard dissimilarity matrix in R? Which package to use, and so on... Can anybody help me? Alternatively

Does anyone have a good method for calculating Jaccard coefficients now that the dissimilarity() function is no longer an option?

Dear All, I would like to use the simprof function (clustsig package) but the available distances do not include Jaccard distance, which is the most appropriate for pres/abs community data. Here is the core of the function: > simprof function (data, num.expected = 1000, num.simulated = 999, method.cluster = "average", method.distance = "euclidean", method.transform =

Hi Is there anyone who has successfully resolved the low throughput problem in Guest communication. I am using Xen3.4.1 with PV os kernel 2.6.30-rc6-tip On fedora11. While running netperf benchmark on guests throughput results are very low DomU to DomU    0.29 Mbps Why is it so? What would be the problem. Is there any issue with fc11 platform?

Good morning, I am analyzing a dataset composed by 364 subjects and 13 binary variables (0,1 = absence,presence). I am testing possible association (co-presence) of my variables. To do this, I was trying with cluster analysis. My main interest is to check for the significance of the obtained clusters. First, I tried with the pvclust() function, by using method.hclust="ward" and

I have read everything I can find on how to manipulate a results matrix in R and I have to admit I'm stumped. I have set up a process to extract a dataset from ArcGIS to compute a similarity index (Jaccards) in Vegan. The dataset is fairly simple, but large, and consists of rows = sample area, and columns = elements. I've been able to view the results in R, but I want to get the results

Dear All, It's Eszter again from Hungary. I could not solve my problem form yesterday, so I still have to ask your help. I have a binary dataset of vegetation samples and species as a comma separated file. I would like to calculate the Jaccard distance of the dataset. I have the following error message: Error in rowSums(x, prod(dn), p, na.rm) : 'x' must be numeric In addition:

Hello R, could you explain to me how to resolve this question: If this is a matrix: Element S1 S2 S3 S4 0 0 1 0 1 1 0 1 0 0 2 1 0 0 1 3 0 0 1 0 4 0 0 1 1 5 1 0 0 0 1. How is possible to ompute the minhash signature for each column if we use the following three hash functions:

Hi, I'm trying to use adonis on a subset of data from a dataframe. The actual data is in columns 5:118, and the first four columns are various factors. There are 3 levels of the factor Habitat, and I want to examine differences among only two of them. So I started with: > CoastNear = subset(gel_data, Habitat != "I") The resulting data.frame has three levels for Habitat, but
