Probability density function brilliant
Webb19 sep. 2024 · The probability density function is actually defined by this requirement. In introductory probability courses, you will see the density function defined as the (Riemann) derivative of the cumulative distribution function: f X ( x) ≡ d F X d x ( x) = d d x P ( X ⩽ x) = lim Δ ↓ 0 P ( x < X ⩽ x + Δ) Δ. WebbAs an example, consider the probability density function f ( x) which is zero for negative x and f ( x) = e − x for positive x. Then f ( 0) can be any value we want, e.g. f ( 0) = − 1, without changing the adequacy of f ( x) as a probability density function on ( − ∞, ∞).
