In the global approach to interval estimation, one uses either a global optimization method or a sampling method to assess the bounds of the responses.
global_interval_est allows the user to specify several approaches to calculate interval bounds on the output responses.
lhs - note: this takes the minimum and maximum of the samples as the bounds ego sbo ea Additional Resources
