Abstract:
1. A method comprising: receiving data associated with a plurality of samples, each sample including one or more events, at least some of the samples having a plurality of events, the events associated with one or more traits that characterize the samples, the traits described by correlations among events; determining one or more of the traits, using a routine comprising: selecting a lower co-occurrence threshold; calculating E(i,i), a first number of samples in which a first event EventID(i) occurs; calculating E(j,j), a second number of samples in which a second event EventID(j) occurs; calculating E(i,j), a third number of samples in which EventID(i) and EventID (j) occur together; selecting at least two events EventID(i) and EventID(j) for which E(i,j) divided by the lesser of E(i,i) and E(j,j) is at or below the lower co-occurrence threshold; assigning EventID(i) to a first trait T1; assigning EventID(j) to a second trait T2; associating first trait T1 with one or more first samples; associating second trait T2 with one or more second samples; and recording the association.
