The effect of the partial adjustment by on the evaluation of the adjusted expectation is to revise expectations downwards for , from about 4.85 to 4.71, and upwards for from about 6.58 to 6.91. (These are now, of course, the adjusted expectations for the full adjustment by .) The differences are, in our notation,
Standardising the changes, we have
representing, for each quantity, a change in expectation of 1.96 standard deviations relative to the partial variance resolved. That is, for such a small change in variance we saw a fairly large change in expectation by using the observed two-hour measurement as well as the observed fasting measurement.
