... the right-hand side. Going back to (2.4) we see that this is exactly the value we need in order to ensure that the asymptotic coverage of the band equals 1 − α0 for all x such that α(x, α0 ) ≤ αξ (α0 ). This approach becomes steadily more conservative, for a proportion 1 − ξ of values of x, as we de ...

PROC MIXED: Underlying Ideas with Examples
... Mixed models include a wide array of useful statistical approaches, some new and some quite old. SAS ® PROC MIXED uses an estimation method similar to maximum likelihood called REML estimation. This is a relatively new method and with it comes some new looking output similar to the traditional analy ...
