CI - Confidence Interval

(7/24/89)

PURPOSE

Computes the confidence interval for each point of an average image resulting from adding a particle series. Input are the error probability of the confidence interval and the average and variance files. (Source: Haenicke, MPI Goettingen.)

USAGE

.OPERATION: CI

.AVERAGE: AVA001
[Enter the name of the file containing the average of each averaged image point. This is obtained by using operation 'AS'.]

.VARIANCE: STD001
[Enter the name of the file containing the variance of each averaged image point. This is obtained by using operation 'AS R'.]

.UPPER LIMIT OUTPUT FILE: UCI001
[Enter the name of the file to receive the upper limit for confidence interval associated with the estimated mean for the choice of the error probability.]

.LOWER LIMIT OUTPUT FILE: LCI001
[Enter the name of the file to receive the lower limit for confidence interval associated with the estimated mean for the choice of the error probability.]

.NUMBER OF FILES ADDED: 56
[Enter the number of images added when the average image was formed.]

.ERROR PROBABILITY IN %: 5
[The error probability in % for confidence interval.]
