Re: [R] Different value between R variance and definition ofvariance

Hi! maybe because sample variance has N-1 at the denominator (say degrees of freedom)? so all.equal((sum(x^2) - 100*mean(x)^2)/99, var(x)) ## TRUE but (sum(x^2) - 100*mean(x)^2)/100 # == your value Stef On Wed, Nov 28, 2007 at 09:56:58AM +0100, Tine wrote: Hi! Let us define random varia
