8. Applied to a statistical test that yields approximately correct results despite the falsity of certain of the assumptions on which it is based; also, to a calculation, process, or result if the result is largely independent of certain aspects of the input.

Dorland’s Illustrated Medical Dictionary defines robust: In statistics, a somewhat imprecise term that is applied to a procedure that is relatively insensitive to violations of the assumptions on which it is based or to procedures that are based on weaker (more easily satisfied) assumptions, e.g., nonparametric tests [Whatever that means, ed.].

Stedman’s Medical Dictionary, 27th Edition, defines robustness just as clearly: In statistics, the degree to which the probability of drawing a wrong conclusion from the test result is not seriously affected by moderate departures from the assumptions implicit in the model on which the test is based.

Robust is related to red. It comes ultimately from Indo-European reudh; source of English red. This resulted in Latin robus, which was applied to a particular sort of oak tree with reddish wood. The oak being synonymous with strength, robus in due course came to mean “strength.” This was carried over into the derived robustus, “firm, strong, solid,” from which English gets robust, and also into the verb roborare “strengthen,” source of English corroborate.
