Input variables Categorical/ Continuous Categorical/ Continuous
Split at each node Binary; Split on linear combinations Binary; Split on linear combinations

Pareto analysis – This technique is useful when many decisions need to be made. This helps prioritize which ones should be made first by determining which decisions will have the greatest overall impact.

How does a decision tree helps in problem solving?

Decision trees provide an effective method of Decision Making because they: Clearly lay out the problem so that all options can be challenged. Allow us to analyze fully the possible consequences of a decision. Help us to make the best decisions on the basis of existing information and best guesses.

#### Which method is used in decision tree algorithm?

In order to build a tree, we use the CART algorithm, which stands for Classification and Regression Tree algorithm. A decision tree simply asks a question, and based on the answer (Yes/No), it further split the tree into subtrees.

#### How is pruning done in decision tree?

We can prune our decision tree by using information gain in both post-pruning and pre-pruning. In pre-pruning, we check whether information gain at a particular node is greater than minimum gain. In post-pruning, we prune the subtrees with the least information gain until we reach a desired number of leaves.

What is this popular method tool used for decision making?
