Table 1.
Comparison of average test errors (and corresponding standard errors in parentheses) for Example 1 with respect to one or multiple crosses and three distance measures. The results for naive method, mixture of regression, SSANOVA, resolution-wise regression with fixed smoothness, and resolution-wise regression with CV are listed in the columns from left to right respectively.
