The Madrid Codex, also known as the Tro-Cortesianus Codex (112 pages, 6.82 metres [22.4 feet]) dating to the Postclassic period of Mesoamerican chronology (circa 900–1521 AD).; [14] The Paris Codex, also known as the Peresianus Codex (22 pages, 1.45 metres [4.8 feet]) tentatively dated to around 1450, in the Late Postclassic period (AD 1200 ...
Like other decision trees, CHAID's advantages are that its output is highly visual and easy to interpret. Because it uses multiway splits by default, it needs rather large sample sizes to work effectively, since with small sample sizes the respondent groups can quickly become too small for reliable analysis.
Decision trees are a popular method for various machine learning tasks. Tree learning is almost "an off-the-shelf procedure for data mining", say Hastie et al., "because it is invariant under scaling and various other transformations of feature values, is robust to inclusion of irrelevant features, and produces inspectable models.
Decision trees can also be seen as generative models of induction rules from empirical data. An optimal decision tree is then defined as a tree that accounts for most of the data, while minimizing the number of levels (or "questions"). [8] Several algorithms to generate such optimal trees have been devised, such as ID3/4/5, [9] CLS, ASSISTANT ...
An alternating decision tree (ADTree) is a machine learning method for classification. It generalizes decision trees and has connections to boosting . An ADTree consists of an alternation of decision nodes, which specify a predicate condition, and prediction nodes, which contain a single number.

A fast-and-frugal tree is a classification or a decision tree that has m+1 exits, with one exit for each of the first m −1 cues and two exits for the last cue. Mathematically, fast-and-frugal trees can be viewed as lexicographic heuristics or as linear classification models with non-compensatory weights and a threshold.
