From page 177...
... In actuality, the percentage of horizontal positions contained within the 2 arms value varies between approximately 95.5 percent and 98.2 percent, depending on the degree of ellipticity of the error distribution. Circular Error Probable (CEP)

From page 178...
... Here the level of significance associated with the recovery of position is tied to the uncertainty of the measurements used. This is a function of geometry between the receiver and the tracked satellites.
