  We present a theoretical and empirical analysis of a number of bibliometric
indicators of journal performance. We focus on three indicators in particular,
namely the Eigenfactor indicator, the audience factor, and the influence weight
indicator. Our main finding is that the last two indicators can be regarded as
a kind of special cases of the first indicator. We also find that the three
indicators can be nicely characterized in terms of two properties. We refer to
these properties as the property of insensitivity to field differences and the
property of insensitivity to insignificant journals. The empirical results that
we present illustrate our theoretical findings. We also show empirically that
the differences between various indicators of journal performance are quite
substantial.
