WebThe Standard Deviation is Sub-Additive A sub-additive risk measure ρ[X] satisfies the following: ρ[X + Y] # ρ[X] + ρ[Y] A super-additive risk measure satisfies: ρ[X + Y] $ ρ[X] + ρ[Y] When only equality holds, the risk measure is additive. The variance (var [X]) of two random variables with positive covariance (cov [X,Y] > 0) is a super- WebThe standard deviation is a measure of "spread", i.e. how far values vary from the mean. Adding the same fixed number to each output changes the "location" of each data point, but it doesn't change the spread. Multiplying each number by a constant doesn't change the location, but it changes the spread: multiplying by $2$ changes a gap of $7$ to ...
