Figure 3From: Some novel inequalities for fuzzy variables on the variance and its rational upper bound The credibility distribution of \(\pmb{\xi\sim \mathcal{T}(a, b, c)}\) in Example 3 . The piecewise function \(\Phi(x)\) is the credibility distribution of \(\xi\sim \mathcal{T}(a, b, c)\) whose values are 0, 0.5, and 1 when x are a, b, and c, respectively.Back to article page
