For unequal sample sizes, the confidence coefficient is greater than 1 " ?.
2.
The confidence coefficient for the set, when all sample sizes are equal, is exactly 1 " ?.
3.
To fix the confidence coefficient at 1-\ alpha, the Working Hotelling approach employs an F-statistic:
4.
:" A study reports that college students work, on average, between 4.63 and 12.63 hours a week, with confidence coefficient . 95.
5.
The simultaneous confidence coefficient is exactly 1 " ?, whether the factor level sample sizes are equal or unequal . ( Usually only a finite number of comparisons are of interest.
6.
The lower confidence limits with joint confidence coefficient P for the p treatment effects m _ { i }-m _ { 0 }, ( i = 1 . . . p ) will be given by:
7.
However, when | X _ 1-X _ 2 | \ geq 1 / 2, intervals from the first procedure are " guaranteed " to contain the true value \ theta : therefore, the nominal 50 % confidence coefficient is unrelated to the uncertainty we should have that a specific interval contains the true value.
8.
Like the closely-related Scheff?s method in the analysis of variance, which considers all possible contrasts, the Working Hotelling procedure considers all possible values of the independent variables; that is, in a particular regression model, the probability that all the Working Hotelling confidence intervals cover the true value of the mean response is the confidence coefficient.
