I made a decision tree with party plot in R but don't really know what it's telling me. The data is about the indian startup ecosystem. I don't know what nodes mean.
The tree displays the subsets found through recursive partitioning. The dependent variable in every resulting subset is visualized by a box plot.
As an example, consider node 10:
InvestmantnType
and had a Date.dd.mm.yyyy
in 15, 2018, or 2019.Amount.in.USD
for these 95 observations. You can extract the variable importance from tree$variable.importance
or you can simply summary(tree)
. Variable importance tells us which variables are most important for the models to make decisions.
