Example 2. However, there is no general framework that comprises different data types including finite and infinite count data, potentially heavy-tailed continuous data, and combinations of discrete and continuous data and at the same time, ensures a rigid Such a function must have the properties that f(x i) ≥ 0, for all i, and X i f(x i) = 1. >> 2 0 obj Tabulation of discrete data, done against a single value, is called as an ungrouped … Mixture of Discrete and Continuous Random Variables What does the CDF F X (x) look like when X is discrete vs when it’s continuous?
