Quantlet: kuva
Description: Makes a picture of a regression tree.

Usage: kuva (cs {, stri})
Input:
cs list of vectors: data structure which represents a binary tree and is produced by cartsplit procedure, contains vectors .. cs.val, cs.vec, cs.mean, cs.ssr, cs.nelem. See cartsplit for the description of cs.
stri string: optional argument, either missing, "nelem", "ssr" or "mean".

Note:

Example:

; loads the library xclust

library ("xclust")

;let us generate a tree by cartsplit procedure

x1=#(0,0,0,0,1,1,1,1,1,2)

x2=#(0,0,0,0,0,0,0,1,1,1)

x=x1~x2

y=#(0,0,0,0,100,100,100,120,120,120)

cs=cartsplit(x,y,#(0,1))

cs

kuva(cs)

kuva(cs,"mean")

Result:
