  We measure the ordinary and the anomalous Hall effect in a set of yttrium
iron garnet$|$platinum (YIG$|$Pt) bilayers via magnetization orientation
dependent magnetoresistance experiments. Our data show that the presence of the
ferrimagnetic insulator YIG leads to an anomalous Hall like signature in Pt,
sensitive to both Pt thickness and temperature. Interpretation of the
experimental findings in terms of the spin Hall anomalous Hall effect indicates
that the imaginary part of the spin mixing interface conductance
$G_{\mathrm{i}}$ plays a crucial role in YIG$|$Pt bilayers. In particular, our
data suggest a sign change in $G_{\mathrm{i}}$ between $10\,\mathrm{K}$ and
$300\,\mathrm{K}$. Additionally, we report a higher order Hall effect, which
appears in thin Pt films on YIG at low temperatures.
