A new method for sensitivity analysis of model output is introduced. It is based on the Fourier Amplitude Sensitivity Test (FAST). This new method is superior to the existing global sensitivity analysis methods - with the exception of Sobol' sensitivity measure - in that it allows the computation of the total contribution of each input parameter to the output's variance. The term total here means - in the terminology of the theory of experimental design - that the parameter's main effect as well as all the higher order interaction terms involving that parameter are included.
