\label{fig:Test1Ht}  Summary statistics at each genome position for a simulated data set. The small green circles and blue pluses are the $Ht(D_i)$ values and $Ht(N_i)$ values, respectively. For genome site $i$ that belongs to the signal set, its $Ht(D_i)$ value is highlighted in a large red circle. The dotted line ($d_0 = 3.082$) is the threshold obtained using our method. The five red circles on the top left correspond to the true substitution sites: 1, 21, 41, 61, 81. There is a clear separation between signals and the rest of the sites.
