class MHCombinedProposal[A](val proposals: Seq[MHProposalGenerator[A]]) extends MHProposalGenerator[A]

Container for multiple ProposalGenerators stacked together, applied one after the other. It serves the same purpose as CombinedProposal, but is made to work together with the MHSample. In particular, it creates a generatedBy String, which references the name of all the proposals that are combined.

def forType[T](implicit conversion: ParameterConversion[A, T]): MHProposalGenerator[T]

Applies a parameter conversion of the sampled type. With this mechanism it is, for example possible to derive a generator for a Type T (e.g. ShapeParameters) from a generator that samples only DenseVectors.

returns a new ProposalGenerator, with a new label. This is useful to summarize complicated labels in composed proposal generators
