Webb11 apr. 2024 · This reduced correlation can reduce the variance of a theoretical portfolio. In this sense, an individual investment’s return is less important than its overall contribution to the portfolio. Webb19 maj 2024 · Theorem: Let X X be a random variable following a gamma distribution: X ∼ Gam(a,b). (1) (1) X ∼ G a m ( a, b). Then, the variance of X X is Var(X) = a b2. (2) (2) V a r ( X) = a b 2. Proof: The variance can be expressed in terms of expected values as Var(X) = E(X2)−E(X)2.

Webb1 dec. 2024 · The power law exponent for Bitcoin volatility conforms to a theoretical variance. However, we do not find such evidence for the volatility processes of stablecoins. While our results suggest that theoretical means of stablecoin volatility processes exist, their corresponding variances are infinite, which indicates statistical instability. http://darrenkuro.com/wp-content/uploads/2024/01/Darren-Biostatistics-Past-MCQ-Compilation.pdf
