Dear Dimitri, if you wish single the correlations, can use the following script: a<-1:10 b<- rnorm(10) c<- rbinom(10,8,0.3) d<- rpois(10,8) corr<-cor( cbind(a,b,c,d) ) round(as.dist(corr),2) # or only as.dist(corr) a b c b 0.07 c 0.19 -0.26 d -0.16 -0.13 -0.41
regards, Felipe Hi! I was wondering if there is a package in R that allows one to create a multivariate data set with pre-specified intercorrelations among variables, e.g., a set of 4 variables (with a length of N each), such that the correlations between variables are: a b c d a 1 r1 r2 r3 b 1 r4 r5 c 1 r6 d 1 Thank you very much!
