Pointwise 95% … WebThe resulting confidence bands are known as the Working–Hotelling–Scheffé confidence bands. Like the closely related Scheffé's method in the analysis of variance, which considers all possible contrasts, the Working–Hotelling procedure considers all possible values of the independent variables; ...

WebP ( F n ( x) − d ≤ F ( x) ≤ F n ( x) + d for all x) = 1 − α. We could stop there and claim that: F n ( x) − d ≤ F ( x) ≤ F n ( x) + d for all x. is a 100 ( 1 − α) % confidence band for the unknown distribution function F ( x). There's only … WebIt can be shown that the probability is 1 − α that all confidence limits of the type are simultaneously correct, where as usual N is the size of the whole population. Draper and Smith, in their 'Applied Regression Analysis' (see references), indicate that 'r' should be in the equation in place of 'r-1'.
