Milestone
The ten-dimensional simple function from Linkletter et al. (2006)1 is a linear model defined as follows:
where$\boldsymbol{x} = { x_1, x_2, x_3, x_4 }$ is the vector of input variables modeled as an independent uniform random variable in $[0, 1]^4$ . $\epsilon$ is a random error generated from $\mathcal{N}(\mu = 0.0, \sigma^2=0.05)$ . Although the model is defined to be of ten-dimensional, only four input variables are active.
In the paper, the response is standardized (with mean 0 and standard deviation 1.0), but we will skip this in the implementation of the function in UQTestFuns. The candidate name for this function is
LinkLetter2006Simple
.The model is used as a test function in the context of sensitivity analysis.
