Calculates a scale of CART histograms. The histograms in the scale have partitions of growing cardinality. Returns a sequence of estimates as piecewise constant functions and optionally as level set trees. Optionally a shape tree for a level set of each estimate is calculated.
1 2 | lstseq.cart(treeseq, maxleaf=NULL, lstree=NULL, level = NULL,
indvec = NULL)
|
treeseq |
output of function "prune" |
maxleaf |
the maximal cardinality of the partitions of the histograms in the sequence |
lstree |
if NULL, then level set trees are not calculated |
level |
if NULL, then shape trees are not calculated; if positive number, then it is the level of the level sets for which the shape trees are calculated |
indvec |
a vector of indeces; chooses a subset of the complete sequence of subhistograms of the overfitting histogram |
A list with components
lstseq |
a list of level set trees |
pcfseq |
a list of piecewise constant functions |
stseq |
a list of shape trees |
hseq |
a vector of smoothing parameters corresponding to the members in the sequences; the smoothing parameter is the cardinality of the partition |
