getVHat: Estimator of tree proxy variable
In mbask/RBSperformance: An R package to aid in RBS estimations

Description Usage Arguments Details Value Note See Also

Recursively computes the estimator of the proxy variable at the tree level, from a terminal segment identified by 'segmentId' in a vector of 'treeSegments' ids

  getVHat(segmentId, treeSegments, treeParentSegments,
    pathProbabilities, segmentTargetVars, vHat = 0,
    pathProb = 0)

`segmentId`	the segment identification id
`treeSegments`	a vector of unique segment identification ids
`treeParentSegments`	a vector of parent identification ids; a tree segment must have a match in treeParentSegment or a NA value if the segment is the butt of the tree (ie its first segment)
`pathProbabilities`	a vector of segment probabilities
`segmentTargetVars`	a vector of segment proxy variables (eg volume, biomass, etc.)
`vHat`	the estimator of the target variable at the tree level (defaults to 0, not to be set by the end-user function call)
`pathProb`	the cumulative probability of the 'segmentId' (defaults to 0, not to be set by the end-user function call)

The proxy variable may be segment volume, biomass, Carbon content or whatever else

a list of two elements, the estimator of tree proxy variable based on the 'segmentId' segment, and its cumulative probability (the product of all segments individual probabilities down to the butt)

A tree segment must have 1 parent segment. The treeParentSegments vector must hold 1 NA value, corresponding to the first segment
