Recent studies have assumed that such unobserved factors vary spatially to give spatial frailty survival models.
Because we expect SES to vary spatially and be a spatial confounder, analyzing ASD without respect to ID may mask the true spatial patterning of disease.
Soils are natural elements of weathered landscapes whose properties may vary spatially.
The rake angles vary spatially and temporally within 127° ± 45°.
Both surface roughness and refractive index may vary spatially.
The chemical, physical and biological characteristics of groundwater vary spatially and temporally.
GIC values vary spatially much from site to site in a network.
GWR is a statistical technique that allows the modeling of processes that vary spatially.
Land use can influence river pollution and such relationships might or might not vary spatially.
In offshore conditions, however, both the soil profile and soil properties vary spatially.
As with air pollution, trends in visibility vary spatially and temporally.
