DPTreeDensity function

Calculating sub-partition probabiltiy measures for a realized distribution from D-P tree.

DPTreeDensity returns the probablity measures in the finest sub-partitions of a realized distribution from D-P tree prior/posterior.

DPTreeDensity(Z)

Arguments

• Z: An array of dimension of $2^m$ by $2^m$ by m, m being the approximation level. Realized Z's for all partitions at each level, as returned by RealizeDPTree.

Returns

A $2^m$ by $2^m$ matrix. Normalized measures for all $2^m$ by $2^m$ sub-partititons on copula space given by the realized distribution from D-P tree.

Examples

dp.rlz <- RealizeDPTree(DPTreePrior(m=2, z=1))
DPTreeDensity(dp.rlz)
