Uncertainty propagation with singularity time surrogate models.
The estimated global sensitivity indices of (a) tg and (b) tz with respect to the uncertain parameters. The estimated PDF of (c) tg and (d) tz based on 1e+6 surrogate model evaluations, which only requires approximately 1 second of CPU time.
