[R] how to extract the maximum from a matrix?
Dear UseRs, I have a very simple question. I have a big matrix (say x) including probabilities (values in (0,1)). I have to store in a list the names of the row and the column where max(x) is located. How can I proceed?

[R] problems perfroming the vuong test
Dear All, I am using the function vuong of the package pscl to compare 2 non nested glm models with a numeric response. I did the following m1-glm(y ~x ,data=xxx) m2-glm(y ~z , data=xxx) When calling the vuong function I get the following message: vuong(m1,m2) Error in predprob.glm(m1) : your object of class glm is unsupported by predprob.glmyour object of class lm is unsupported by predprob.glm My guess is that this function does not support numeric response! How can I solve the problem? Any help will be really appreciated. mirko __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R] Voung test implementation in R
Dear All, I would like to know if the Voung test (Voung; Econometrica, 1989) to compare two non-nested regression models has been implemented in R.

[R] t-test for standard deviations
Dear R-users, I am new to the list and I would like to submit (probably) a stupid question: I found in a paper a reference to a t-test for the evaluationg the difference between the standard deviations of 2 samples. This test is performed in the paper but the methodology is not explained and any reference is reported. Does anyone know where I can find references to this test and if it is implemented in R?
