After entering data for each data set in the data grid (Enter data in the data grid), perform a regression by clicking the Regress Data icon
.
Review the results in the grid for the each model (Grid).

Regression tries to minimise the error across all the data sets. It may not be possible to exactly match the entered value in the data grid to the recalculated value determined from the Base + Delta values. After regression, the recalculated (fitted) value is shown for each property in the top right corner of the cell in the data grid. When R2is 1 then the values are equal.
