1. A method of evaluating clustering in case control data for a plurality of individuals taking into account dynamic location information, comprising:

  • establishing a set of space time coordinates for each individual, the set of space time coordinates being indicative of a geographic location of a residence of the individual at a beginning time and an ending time;

    establishing a case control identifier for each individual, the case control identifier having a first control value if the individual is a case and a second control value if the individual is not a case;

    establishing a neighbor relationship value between each individual and the other individuals, wherein the neighbor relationship value between one individual and another individual has a first relationship value, if the one individual and the another individual are neighbors according a set of predetermined criteria and a second relationship value are not neighbors; and

    , for at least one case individual whose case control identifier has the first value, establishing a spatially and temporally local case-control cluster statistic as a function of the set of space time coordinates of each individual, the case control identifier, and the neighbor relationship values between the one case individual and the other individuals.
