Trend surface analysis

{{Short description|Mathematical technique used in environmental sciences}}

File:RSS troposphere stratosphere trend.pngTrend surface analysis, also known as trend surface mapping, is a mathematical technique used in archaeology and environmental sciences such as geology and soil science. The method involves using low-order polynomials of spatial coordinates to estimate a regular grid of points from scattered observations such as archeological finds or soil survey results.{{Citation |last=Agterberg |first=Frits P. |title=Trend Surface Analysis |date=1984 |work=Spatial Statistics and Models |pages=147–171 |editor-last=Gaile |editor-first=Gary L. |url=http://link.springer.com/10.1007/978-94-017-3048-8_8 |access-date=2024-04-20 |place=Dordrecht |publisher=Springer Netherlands |language=en |doi=10.1007/978-94-017-3048-8_8 |isbn=978-90-481-8385-2 |editor2-last=Willmott |editor2-first=Cort J.}}
