A method and apparatus for detecting and correcting inaccuracies in curve-fitted models are provided. With the apparatus and method, humps and dips in a curve fit of actual simulation and/or empirical data are identified. After having identified the humps and dips, an analysis is performed on the humps and dips to determine if they are large enough to warrant correction. Such a determination, in a preferred embodiment, involves taking an absolute value of a difference between a value at an edge point of the hump or dip and a value at the maximum or minimum point on the hump or dip, and comparing the absolute value of the difference to the value at the edge point. If the comparison indicates that the absolute value of the difference is greater than the value at the edge point by a threshold amount, then the hump or dip is determined to be large enough to require correction. If the hump or dip is determined to be large enough to require correction, then the source of the simulation and/or empirical data is modified to taking corrective action to improve the curve fit between the edge point and the next actual simulation and/or empirical data point. This process may be repeated for each hump or dip in the curve fit and may be iterated with each new set of simulation and/or empirical data generated.
