mclust: modelName="E" vs modelName="V"
Hi, 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), modelNam...

R crashes using the em function of package mclust (PR#7719)
Hi, I got the same problem like http://tolstoy.newcastle.edu.au/R/devel/04/11/1204.html R crashes when I use the em function from the mclust package on univariate data and on a special case on bivariate data (when the matrix is not provided as written in the manual). It seems as if the problem is the format of the data to be analyzed. Operating System: Windows XP (SP2) R version: R-2.0.1 The

A Few MCLUST Questions
Hello everyone. I have a few MCLUST questions and I was hoping someone could help me out. If you’re an MCLUST user, they will likely be pretty easy to answer. Thanks in advance for any help. Ken What are the pros/cons of starting a finite mixture model at the “m” step versus the “e” step (where “m” is the maximization step and “e” is the expectation step of the EM algorithm)? In

Mclust problem with mclust1Dplot: Error in to - from : non-numeric argument to binary operator
Dear list members, I am using Mclust in order to deconvolute a distribution that I believe is a sum of two gaussians. First I can make a model: > my.data.model = Mclust(my.data, modelNames=c("E"), warn=T, G=1:3) But then, when I try to plot the result, I get the following error: > mclust1Dplot(my.data.model, parameters = my.data.model$parameters, what = "density") Error in to - from : non-numeric argument to binary operator Also, I'd like to allow for ea...

center option of basehaz in survfit
I have a very general question about what the centering option in basehaz does to factors. (basehaz computes the baseline cumulative hazard for a coxph object using the Breslow estimator). Lets say I'm interested in a survival model with two (dichotomous) factors and a continuous covariate. Variable Possible Values Factor1 0 or 1 Factor2 0 or 1

Disable Migration creation in generate Model
Hi.... Is there some way to configure Rails to not create a db/migrate/###_model_name.rb when I do a script/generate model ModelName? It''s a little annoying when I''m setting up a new application since I prefer creating all the first tables in a 001_inital_schema.rb file. Then when I generate models for those tables I get migration scripts for all of them again that I have to

simple scaffold question
How do I get scaffold to generate code for a table whos name is not plural of the modelname I give to it.

Indexing weirdness
Hi, I''m having some problems with acts_as_ferret and indexing. I''ve got a simple 5 column table, and a corresponding Ruby model. I loaded 9 rows directly into the table using mysql (for live it''ll be about .5mil rows) and configured a Rails search page along the exact same lines as ferret_demo.

generating a matrix after a for loop..
Hi all, I have to ask this and I know that the reason is that I am a newbie with R programming. So apologize if it is too obvious but I didn't find an answer after googling and reading "An introduction to R". So i have return data from 30 instruments and I am fitting a mixture of normal distributions for the asymmetric marginal distributions and then simulating from those
