Data were taken and modified from Arditi and Akçakaya (1990) to estimate mutual interference, m, and its variance, var(m).  Variances of mutual interference parameters were calculated as the square of the standard errors reported in Table 2 of Arditi and Akçakaya (1990).   Mutual interference estimates and their variances were based on Method II model fits reported by Arditi and Akçakaya (1990).  Study provides the citation for the paper where original data were obtained by Arditi and Akçacaya.  For additional detail see Arditi and Açkakaya (1990).
