Nonparametric Bayes Wrapping Up Sensitivity

Remote RStudio configuration (keep forgetting options and ports).

ssh -o "ExitOnForwardFailure yes" -f -N -L 1234:localhost:8787 one

Initialize runs for sensitivity, looping over parameters and data. See:


ggplot(yields_dat) + geom_density(aes(value))

Compare over 12 simulation configurations with different parameters and different training data, the GP does consistently well. Only one case has relatively poor outcomes.
