WebHow do you calculate normal CDF? The CDF function of a Normal is calculated by translating the random variable to the Standard Normal, and then looking up a value from the precalculated “Phi” function (Φ), which is the cumulative density function of the standard normal. The Standard Normal, often written Z, is a Normal with mean 0 and ... WebFirst, we find F(x) for the possible values of the random variable, x = 0, 1, 2: F(0) = P(X ≤ 0) = P(X = 0) = 0.25 F(1) = P(X ≤ 1) = P(X = 0 or 1) = p(0) + p(1) = 0.75 F(2) = P(X ≤ 2) = P(X = 0 or 1 or 2) = p(0) + p(1) + p(2) = 1 Now, if x < 0, then the cdf F(x) = 0, since the random variable X will never be negative.
