t.test() on a list
I have a list, myList, with each of its 9 components being a 15X15
matrix. I want to run a t-test across the list for each component in
the matrix. For example, the first t-test is on myList[[1]][1, 1],
myList[[2]][1, 1], ..., myList[[9]][1, 1]; and there are totally 15X15
t-tests. How can I run these t-tests in a simple way?
TIA,
Gang

Covariance matrix in R with non-numeric variables
Dear R help forum members,
I am modeling a gaussian distribution for a computational biology application and I am working in the statistical package "R". In this regard, my problem is that I have to construct a covariance matrix with variables (non-numeric) and the covariance matrix is to be used in an maximizers of the likelihood function to predict the variables in the matrix. I am
