Webfreedom and Birge ratio R B = p χ2/ν = 1.26. In order to make the data consistent, it is usually assumed that the quoted uncertainties are wrong by a common scale factor. By … Webearly 2008 to the present a Birge ratio ranging from 0.9 to 1.1 over time is obtained indicating that the data is generally consistent with the stated total uncertainties. The relative microwave lensing bias is not large enough at this time to have a significant impact on the Birge ratio. However, if a large
Webmeans. The consistency of the CRVs was checked using the χ2 test and Birge ratio. The confidence coefficient E of individual laboratories was calculated for CRVs, which did not pass the Birge ratio test. Results of laboratories with E > 1,5 were not included in the calculation of the corrected CRVs. WebRaymond Thayer Birge (March 13, 1887 – March 22, 1980) was an American physicist. Career.
