I am creating covariance matrices from sets of points, and I am having frequent problems where I create matrices that are non-positive definite. I've started using the corpcor package, which was specifically designed to address these types of problems. It has solved many of my problems, but I still have one left. One of the matrices I need to calculate is a cross-covariance matrix. In other words, I need to calculate cov(A, B), where A and B are each a matrix defining...

Hello, I'm attempting to create a data frame with correlations between every pair of variables in a data frame, so that I can then sort by the value of the correlation coefficient and see which pairs of variables are most strongly correlated. The sm2vec function in the corpcor library works very nicely as shown here: library(Hmisc) library(corpcor) # Create example data x1 = runif(50) x2 = runif(50) x3 = runif(50) d = data.frame(x1=x1,x2=x2,x3=x3) label(d$x1) = "Variable x1" label(d$x2) = "Variable x2" label(d$x3) = "Variable x3" # Get co...

Hi, If a matrix is not positive definite, make.positive.definite() function in corpcor library finds the nearest positive definite matrix by the method proposed by Higham (1988). However, when I deal with correlation matrices whose diagonals have to be 1 by definition, how do I do it? The above-mentioned function seem to mess up the diagonal entries. [I haven't seen this complic...

...tats classes a lot. It did in mine, and a glance through the R-help archives suggests I'm not alone. I finally found a reference describing the calculation, and wrote the following R function to perform it. Note that the function depends on a partial correlation function found in library(corpcor). kmo.test <- function(df){ ### ## Calculate the Kaiser-Meyer-Olkin Measure of Sampling Adequacy. ## Input should be a data frame or matrix, output is the KMO statistic. ## Formula derived from Hutcheson et al, 1999, ## "The multivariate social scientist," page 224, ISBN 0761952012 #...

Dear R users, I am not good in R-language programming. So, i need your help. I want to convert my lower-triangle value of symmetry matrix into a vector with their row and column name. I found a function called "sm2vec" in "corpcor" package but it give only a vector of values but not row and column names. But i also want ROW and COLUMN name together with their corresponding values. To make more clear,  For example: Suppose i have a symmetric matrix with lower-triangle value with 5 variables (eg. a - e). But in real, i h...

I've seen that this question has been asked before, in the archives, but I haven't been able to find a workable answer. This may be a failure to understand the statistics! The problem is that, while I can easily get partial correlation values out of corpcor, how do I get significance values? Surely the significance of a partial correlation between two variables isn't the same as the simple bivariate correlation significance (cor.test)? As I said, I may be misunderstanding the stats. And just to round out the scenario, I should mention that...

Hi R users, I want to calculate the partial correlation (first or second order) and their corresponding significance test (p-value). I used > library(corpcor) and "cor2pcor" function to calculate partial correlation but could not calculate "p-value". If some one knows the R package or function to calculate corresponding "p-value", It will be great help. Thanks   Sincerely, Ram Kumar Basnet Graduate Student Wageningen Unive...
