Calculating a Partial Dependency Plot with Prediction Intervals for an SAR Model in R Introduction Spatial autoregressive (SAR) models are widely used in geography and spatial analysis to model the relationship between variables at different locations. These models are particularly useful when dealing with spatial data, as they can capture the spatial autocorrelation present in such data. However, one of the limitations of SAR models is that they do not provide a straightforward way to visualize the effect of individual predictor variables on the outcome variable.
