Space-time interaction

Interaction methods are sensitive to patterns where pairs of cases near to one another in space also occur at about the same time. Disease processes producing this pattern include infectious diseases and illnesses caused by exposure to toxic materials.

Are your data rates or case locations?

Notes: Choose rates when the data are rates in areas (e.g. counties) through time (e.g. by month). Select case when the data are the space-time locations of cases, such as place of residence and date of diagnosis or death.
