Linkletter et al. (2006) No Signal Function


Dimensions: 10

This function is used for input variable screening, to see how well a method can identify a lack of signal. As mentioned in Linkletter et al. (2006), Welch (1992) pointed out that it is difficult to distinguish between a model with no active factors and one with all active factors. A small error term ε ~ N(0, 0.052) is added to the response.

Input Domain:

This function is evaluated on the scaled input domain xi ∈ [0, 1], for all i = 1, …, 10.
