Confidence band formula
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'. WebTesting the y-intercept Example 2: Test whether the y-intercept is 0. We use the same approach as that used in Example 1 to find the confidence interval of ŷ when x = 0 (this is the y-intercept). The result is given in …
