# Parameter Screening

Quickly identify important vs unimportant parameters.

## Execution Guidance

Use Morris method (one-at-a-time with random trajectories) to quickly identify which parameters have large effects (high mu*) and which have nonlinear/interaction effects (high sigma). Eliminate clearly unimportant parameters.
