SSM: SSM: A package for fitting smooth supersaturated models...

Description SSM functions

Description

The SSM package provides an S4 class to represent smooth supersaturated models, along with functions for fitting SSM to data, computing Sobol indices for the SSM and estimating metamodel error with a Gaussian process.

SSM functions

There are three important functions in the package.

fit.ssm returns an SSM object that fits an SSM to the data and, by default, computes the Sobol indices, and Total interaction indices of the model. Optionally, the metamodel error can be estimated using a Gaussian process. The fitted SSM smooths over [-1, 1]^d and uses a hierarchical basis of 20*d+n Legendre polynomials by default but the function is highly customisable.

predict.SSM returns the model prediction at a point, including a credible interval if a metamodel error GP has been fit.

plot.SSM plots the main effects of the SSM.
