WebNov 24, 2024 · Empirical measures can be analysed in two forms. The first you have seen above: the uniform dice roll distribution next to the empirical histogram of the dice rolls. The other form is a cumulative distribution function*, which can be used to identify the probability that an outcome will be less than or equal to a certain value. WebThe cumulative distribution function (CDF) of X is F X(x) def= P[X ≤x] CDF must satisfy these properties: Non-decreasing, F X(−∞) = 0, and F X(∞) = 1. P[a ≤X ≤b] = F X(b) −F X(a). Right continuous: Solid dot on at the start. If discontinuous at b, then P[X = b] = Gap. Relationship between CDF and PDF: PDF →CDF: Integration
