Relations between p
based on fitting the model to 3 individual noise-free data sets with different inputs. The fittings for p30 to each data set were made by fixed p28 and p29 with different values. Three zero residual surfaces are shown: the green plane is based on 1st data set, the red plane 2nd data set, and the blue plane 3rd data set. The three planes cross exactly at the true parameter point.
