regF_gen

Creates the regression function for the GP mean.

Multi-Fidelity emulator for data from computer simulations of the
same underlying system but at different input locations and fidelity level,
where both the input locations and fidelity level can be continuous. Active
Learning can be performed with an implementation of the Integrated Mean Square
Prediction Error (IMSPE) criterion developed by Boutelet and Sung (2025, <doi:10.48550/arXiv.2503.23158>).
