confidence region

— An area within which the actual values of two or more variables are likely to lie

Full forklaring:

A confidence region is similar to a confidence interval, but is calculated for two or more variables at the same time; for example, the difference in cost and the difference in the effectiveness of two treatments in a cost effectiveness analysis.

If a set of measurements, such as the variables used to estimate an incremental cost-effectiveness ratio, were repeated many times and a confidence region calculated in the same way for each set of measurements, then a certain percentage of the time (typically 95%), on average, the confidence region would include the point representing the actual values of the cost and the effectiveness.
