Figure 7.

Fit parameters for (RQGS) and (FQPS) models. Dependence of the modified Gumbel parameters on the subject/query length ratio LS/LQ. The vertical line corresponds to Figure 5, where LS = LQ. (a): λ describes the bulk of the distribution (see Figure 5a) left). For LS >LQ, λ varies only slightly in the subject length. (b): The parameter λ2 characterizes the curvature of the pmf in the tail (see Figure 5b). Large differences between (RQGS) and (FQPS) show up in the case where LS >LQ. λ2 becomes subject-length independent for LS >LQ.
