Table 17: Test of out—of-sample explanatory power of the extended model of
Schmid and Zagst for non-defaultable yields. The last two columns show the
p-values of the F-tests against the null hypotheses a =0and (a, b) =(0, 1). The
results are based on weekly data of Treasury Strips between June 1, 2001, and
August 15, 2001.
