When estimating, under quadratic loss, the location parameter % of a spherically symmetric distribution with known scale parameter, we show that it may be that the common practice of utilizing the residual vector as an estimate of the variance is preferable to using the known value of the variance.

โฆ Synopsis
None of the expressions 'JP', 'FJP" and 'SP', as I use them, entails that S actually believes that P, though it is entailed in each case that such belief is appropriate to S's epistemic situation at t. 1
Where P and Q are any propositions, F any set of propositions, t any time and S any person, the six propositions of the paradox are as follows:
If JP then either SP or there is a F such that FJP. If FJP then J(FJP).
If FJP and Q belongs to F, then JQ. No proposition is (non-superfluously) justified by an infinitely long chain of evidence.
