By combining two alternative formulations of a test statistic with two alternative resamplingschemes we obtain four different bootstrap tests. In the context of static linear regression modelstwo of these are shown to have serious size and power problems, whereas the remaining two areadequate...

We study the performance of two analytical methods and one simulation method for computing in-sample confidence bounds …. They are applicable to the complete class of observation driven models and are valid for a wide range of estimation … provided by our three methods of computing in-sample bounds. The analytical methods may be less reliable than the simulation …
