Sudden changes in allele frequency identified using a jump-diffusion model.

Details are given for loci at which a sudden jump in frequency was inferred with probability at least 1%. The latter value is the inferred probability that the change in allele frequency at a given locus arose from a jump to a random position between 0 and 1, as opposed to arising from a small change to the frequency at the previous locus. Data are shown for the naïve and 17-X immunized experiments; no jumps of this significance were inferred for the CU-immunized experiment.
