Let k1 be the value that you specify for the lower limit and k2 be the value that you specify for the upper limit. By default, the lower equivalence limit, δ1, is given by:
and the upper equivalence limit, δ2, is given by:
Minitab cannot calculate the confidence interval (CI) if either of the following two conditions are satisfied:
By default, Minitab calculates the 100(1 - α)% CI for ρ as follows:
CI = [min(C, ρL), max(C, ρU)]
If you select the option to use the 100(1 - 2α)% CI, then the CI is given by the following:
For a hypothesis of Test mean / reference mean > lower limit, the 100(1 - α)% lower bound is equal to ρL.
For a hypothesis of Test mean / reference mean < upper limit, the 100(1 - α)% upper bound is equal to ρU.
If , then:
