See Example 12.14 on page 460 and Example 12.15 on page 461,
where Example 12.15 demonstrate the cases where few obsevations were deleted.
A couple of notes as fewer observations were deleted (d is smaller):
- The confidence interval shifts downward, reflecting
the greater downward bias in
decreases. This can be attributed as the result of a ``cold start''.
- The standard error of
namely decreases as d decreases. As d
decreases, the number of samples included in the statistics increases,
reducing the error range.
