Shape invariant model approach for functional data analysis in uncertainty and sensitivity studies

Ekaterina Sergienko, Fabrice Gamboa, Daniel Busby

Dynamic simulators model systems evolving over time. Often, it operates iteratively over fixed number of time-steps. The output of such simulator can be considered as time series o…
