"Quite apart form whether variance or standard deviation is sensitive to outliers, there are very specific calculations which require it, and if they do, it should be calculated in a numerically stable manner.
Whoever wrote that variance computation…"
"Following up on Mirko's comment, has the numerically unstable computation of sample variance in Hadoop/Mahout by E(X)^2-E(X^2) been replaced by a numerically stable computation yet? Numerically stable one-pass methods for computing the…"
"I will just address this one statement "Saturn is about 1 billion miles away from Earth (at its closest), far bigger than Earth, and never visible with the naked eye" and not address its relation to the original question at hand (Saturn…"
