## Linkletter et al. (2006) Simple Function

### Description:

*Dimensions: 10*

This function is used for input variable screening, because only four of its input variables have a non-zero effect on the response. A small error term ε ~ N(0, 0.05

^{2}) is added to the response.

### Input Domain:

The function is evaluated on the scaled input domain x_{i}∈ [0, 1], for all i = 1, …, 10.

### Code:
