WebSep 2, 2004 · A robust design can be defined as a design that is highly efficient for a set of alternative models. Such robust designs may especially be helpful when the best fitting model is not known in advance and the researcher is willing to accept a small loss of efficiency in return for a design that remains highly efficient under alternative models. WebOften, robustness tests test hypotheses of the format: H0: The assumption made in the analysis is true. H1: The assumption made in the analysis is false. This tells us what "robustness test" actually means - we're checking if our results are robust to the possibility that one of our assumptions might not be true.
