The mixture of normals model has been extensively applied to density estimation problems.
This paper proposes an alternative parameterisation that naturally leads to new forms
of prior distribution. The parameters can be interpreted as the location, scale and smoothness
of the density. Priors on these parameters are often easier to specify. Alternatively, improper
and default choices lead to automatic Bayesian density estimation. The ideas are extended to
multivariate density estimation.
