suppose I produce two vectors d1 and d2 using the below scheme which results in a correlation of 0.8716288 between the two vectors. Can I make a precise statement on the proportionality of d1 and d2.
Say I have:
m <- matrix(rnorm(100*100),nrow=100) d1<-as.matrix(dist(m, diag=T, upper = T)) d2<-1.-cor(t(m)) plot(as.vector(d1),as.vector(d2)) cor(as.vector(d1),as.vector(d2))
which results in
correlation of 0.8716288 between d1 and d2
- I'm leaving the definition of proportionality open -- since I personally do not know rigorous definitions of the concept beyond what is taught at grade school
- Would appreciate definitions of proportionality as part of the answer
