constraints from the cosmic microwave background and BOSS, finding the two data sets to be consistent within a flat CDM cosmology using the Bayes factor as well as the prior-insensitive suspiciousness statistic. Combining two low-redshift probes, we jointly analyse the clustering of BOSS galaxies with weak lensing measurements from the Kilo-Degree Survey (KV450). The combination of BOSS and KV450 improves the measurement by up to 45%, constraining σ8 = 0:702±0:029 and S 8 = σ8 pm=0:3 = 0:728±0:026. Over the full 5D parameter space, the odds in favour of a single cosmology describing galaxy clustering, lensing, and the cosmic microwave background are 7 ± 2. The suspiciousness statistic signals a 2:1 ± 0:3σ tension between the combined low-redshift probes and measurements from the cosmic microwave background.
