plot.quint | R Documentation |
Plot function for a quint
object. The plot shows the result of quint
:
a binary tree with (a) splitting variable(s) and split point(s). The colors of the
leaves of the tree correspond to the final subgroups: Subgroup 1 (P1), those
patients for whom the mean treatment outcome (Y) is higher for Treatment A than B,
is GREEN; Subgroup 2 (P2), those patients for whom the mean treatment outcome (Y)
is higher for Treatment B than A, is RED, and Subgroup 3 (P3), those for whom the
mean treatment outcome (Y) is about the same for both treatments, is GREY. Within the
leaves the effect size d is displayed, with its 95 percent confidence interval.
This effect size is the standardized mean difference between Treatment A and B.
The plot function uses the plot method from the package partykit of Hothorn
& Zeileis (2013).
## S3 method for class 'quint' plot(x, digits = 2, ...)
x |
fitted tree of class |
digits |
specified number of decimal places of the splitpoints in the graph (default is 2). |
... |
additional arguments to be passed. |
For categorical variables we recommend to use short names for levels to avoid overlapping labels at split points.
