Table 2

The mean value of the intermediate data.

Features of data number N	Estimated value of abnormal data
N is divisible by 4	Estimated value is the mean of N/2 data in the series
N is divisible by 2 but not divisible by 4	Estimated value is the mean of N/2–1 data in the series
N is not divisible by 2 and N + 1 can be divisible by 4	The estimated value is the mean of (N − 1)/2 data in the sequence
N is not divisible by 2 and N + 1 is not divisible by 4	Estimated value is the mean of (N − 1)/2 − 1 data in the series
