Dealing with Dependent Uncertainty in Modelling: A Comparative Study Case through the Airy Equation

Figure 5

Comparison of the approximations for the expectation on the time-interval in Example 4 by using Fröbenius and Polynomial Chaos. The numerical values obtained by both techniques are indistinguishable graphically. We assume that follows a multivariate Gaussian distribution: where and and are given by (35) corresponding to statistical independence and dependence, respectively.
