A Simple Approach to Emulation for Computer Models With Qualitative and Quantitative Factors

Summary: [This abstract is based on the authors' abstract.] A new approach is proposed for building Gaussian models for computer experiments with qualitative and quantitative factors. The approach uses the hypersphere parameterization model rather than directly solving optimization problems with positive definite constraints. Several examples demonstrate the method’s flexibility and efficiency.
