Sensitivity Analysis for Complex Computer Models Uses regression surface approximations to calculate variance decomposition and total variance sensitivity indices. This package is useful for conducting sensitivity analysis of complex computer codes when model evaluations are somewhat expensive (e.g. take longer than a couple seconds to run) but a reasonable number (50 or more) of model evaluations can be obtained at sampled input values.
