This work presents a Bayesian non-parametric method to reconstruct a smooth field. It is applied to reconstruct the space density of AGN as a function of X-ray luminosity, redshift and obscuring column density, all of which contribute severe selection biases. This method can be applied to a wide variety of 3D data sets (e.g. IFU spectral line fitting) to reconstruct the behaviour of a quantity and its uncertainty while only assuming smoothness across the field.
