Fig. 2

Panels a, d shows the variogram and standardized residuals for the fit using OLS. Panels b, e shows for mixed model regression. Panels c, f shows for linear mixed model with CAR(1). Notice how the fit improves with each new addition. In Panels ac, values in the x-axis represent the distance in time between two measurements and values in the y-axis (vijk) represent the square distance between those two observations [29]
