WebExamples: Decision Tree Regression. 1.10.3. Multi-output problems¶. A multi-output problem is a supervised learning problem with several outputs to predict, that is when Y is a 2d array of shape (n_samples, n_outputs).. When there is no correlation between the outputs, a very simple way to solve this kind of problem is to build n independent models, … WebGoal of this CHAID classification tree. Our goal is to test if the four descriptive variables allow to efficiently predict to which species a flower corresponds, and in this case, to identify rules that would help to classify the flowers on the basis of the four variables.

Chi-square automatic interaction detection (CHAID) is a decision tree technique based on adjusted significance testing (Bonferroni correction, Holm-Bonferroni testing). The technique was developed in South Africa and was published in 1980 by Gordon V. Kass, who had completed a PhD thesis on this topic. CHAID can be used for prediction (in a similar fashion to regression analysis, this version of CHAID being originally known as XAID) as well as classification, and for detection of i… WebDec 12, 2024 · CHAID (Ch i-square A utomatic I nteraction D etector) analysis is an algorithm used for discovering relationships between a … WebCHAID is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms CHAID - What does CHAID stand for?
