technology and computing artificial intelligence# What algorithm does Rpart use?

**algorithm**is called

**RPART**(Recursive Partitioning And Regression Trees). This is essentially because Breiman and Co.

Considering this, what is Rpart package in R?

**rpart**: Recursive Partitioning and Regression Trees Recursive partitioning for classification, regression and survival trees. An implementation of most of the functionality of the 1984 book by Breiman, Friedman, Olshen and Stone.

**model**that uses a set of binary rules to calculate a target value.It is used for either classification (categorical target variable) or regression (continuous target variable). Hence, it is also known as

**CART**(Classification & Regression Trees).

Similarly, you may ask, what is Rpart Minsplit?

**minsplit** is “the minimum number of observations that must exist in a node in order for a split to be attempted” and minbucket is “the minimum number of observations in any terminal node”. Observe that **rpart** encoded our boolean variable as an integer (false = 0, true = 1).

1 Answer. The **rpart** package's plotcp function plots the Complexity Parameter Table for an **rpart** tree fit on the training dataset. You don't need to supply any additional **validation** datasets when using the plotcp function. It then uses 10-fold **cross**-**validation** and fits each sub-tree T1
