Subject: find variation of a binary matrix
Hi:
I want to calculate how much the values in a binary matrix varies, and
for that I apply the sd() method.
mat <- matrix(c(1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 1, 1), nrow=4, ncol=3)
stddev <- sd(dist(mat, method="binary"))
And i get the following answer:
stddev
[1] 0.3442652
Is this correct? Or there is a better way out?
Bests:
John
