Trend Surface Analysis of Matrix Data
The analysis output includes the calculated trend grid, the residuals grid, ANOVA report for significance of regression of
-order polynomial trend surface, and XYZ estimates and errors.
A Graphical Example of Applying Trend Surface Analysis to Matrix Data
(a) A contour plot of a matrix dataset.
(b) A contour plot of 6
-order trend generated from the original matrix data in (a).
A plot of the residuals, i.e., deviations from the 6
-order trend in (b)
