measure. The existing measure is just the maximum of the posteriori
measure for a certain procedure of parameter selection or a given
function for determining weights. The posteriori reliability
measure require$ little additional amount of computation, so is also
feasible to be used in practice. Formula (14) and (16) can be used
to compute the posteriori reliability measure in the case of .
adopting robust methods. The derivation of the formulai unciis
that finding the explicit relation between the final weights and the
least squares estimators of additional parameters obtained from the
preliminary adjustment may be the key to translating the existing
reliability theory wholly to the case of using robust methods.
The paper has set forth its conceptions only for the simplified
cases. Their extension to more general cases is left for the
forthcoming papers.
