Hello everybody (I'm new here)
I am looking for 2 specific functions. The first one is a variance
formula that does not divide by n-1 (I don't want the unbiased formula,
that's it). In case it does not exist, how do I modify the default
function code? Yes, a workaround would be to multiply
1) I am not sure why you want the biased version but here are two ways
to do this. Also if you have large enough sample size, it would not
matter much.
my.var1 - function(x) mean( (x - mean(x))^2 )
my.var2 - function(x) mean( x^2 - mean(x)^2 )
2) Look at quantiles function. Your
