 We implement three estimators for this task, which map to either samples or a distribution via `predictsamples(est, xs, ys, noisemodel, nsamples)` and `predictdist(est, xs, ys, noisemodel)`, respectively.
 The conversion between samples and a distribution can be done automatically via sampling or fitting a multivariate normal distribution.
