... from one half, then we are inclined to reject H0 . More formally, we let p+ = PH0 (Xi > θ0 ) and p− = PH0 (Xi < θ0 ). Therefore, under H0 , p+ = p− = 0.5. The sign test is implemented as follows: 1. Let Y denote the number of Xi greater than θ0 (in math. notation, Y = #(Xi − θ0 > 0)). Under H0 , Y ∼ ...

Confidence intervals
... 3. Resample the residuals with replacement to generate6a new set of residuals {!∗i }. What this means is that we generate a new set of N residuals where each of N values is one of the original residuals chosen with equal probability. Typically, some of the original residuals will be chosen more than ...
