The gaussian is typically represented compactly as follows. X ∼ N ( μ, σ 2) where. X is a single random variable. μ is the mean of X. σ 2 is the variance of X. The statement, X ∼ N ( μ, σ 2), says that X comes from a gaussian distribution with a mean μ and variance σ 2; μ and σ 2 are called the parameters.
