Set of possible priors used in the ARTIVAsubnet
function for the
number of changepoints (resp. incoming edges) according to a given number
of maximum changepoints maxCP
(resp. incoming Edges maxPred
)
when parameters (alphaCP
, betaCP
for the CPs or
alphaEdges
, betaEdges
for the edges) in function
ARTIVAsubnet
are set to default (alpha=1, beta=0.5).
In the ARTIVAsubnet
procedure, the number of CPs
(respectively the number of incoming edges) is sampled from a
truncated Poisson with mean lambda, where lambda is drawn from an
Inverse Gamma distribution (alpha, beta), see Lebre et al. (2010) for
more details.
