WebbUnlike a probability, a probability density function can take on values greater than one; for example, the uniform distribution on the interval [0, 1/2] has probability density f (x) = 2 for 0 ≤ x ≤ 1/2 and f (x) = 0 elsewhere. The standard normal distribution has probability density WebbThis function, CDF(x), simply tells us the odds of measuring any value up to and including x.As such, all CDFs must all have these characteristics: A CDF must equal 0 when x = -∞, …
