No Evidence for Galactic Latitude Dependence of the Fast Radio Burst Sky
  Distribution
  We investigate whether the sky rate of Fast Radio Bursts depends on Galactic
latitude using the first catalog of Fast Radio Bursts (FRBs) detected by the
Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB)
Project. We first select CHIME/FRB events above a specified sensitivity
threshold in consideration of the radiometer equation, and then compare these
detections with the expected cumulative time-weighted exposure using
Anderson-Darling and Kolmogrov-Smirnov tests. These tests are consistent with
the null hypothesis that FRBs are distributed without Galactic latitude
dependence ($p$-values distributed from 0.05 to 0.99, depending on completeness
threshold). Additionally, we compare rates in intermediate latitudes ($|b| <
15^\circ$) with high latitudes using a Bayesian framework, treating the
question as a biased coin-flipping experiment -- again for a range of
completeness thresholds. In these tests the isotropic model is significantly
favored (Bayes factors ranging from 3.3 to 14.2). Our results are consistent
with FRBs originating from an isotropic population of extragalactic sources.
