Varying gradient model

A varying gradient model is a mathematical approach used to describe how changes in a system or data set are not uniform but fluctuate across different regions. Rather than assuming a constant rate of change everywhere, this model allows the gradient (rate of change) to adapt based on the specific location or conditions. For example, in environmental studies, it can represent how pollution levels change more rapidly in some areas and more slowly in others, providing a nuanced understanding of spatial or temporal variations for better analysis and decision-making.
