Chaid testing
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. Setting up the dialog box to generate a CHAID classification tree WebCHAID. We can use Chi-square automatic interaction detection for classifying categorical variables when we have only categorical predictors. In CHAID, we categorise the data …

CHAID uses a chi-square measurement metric to discover the most important characteristic and apply it recursively until sub-informative data sets have a single decision. Although it is a legacy decision tree algorithm, it's still the same process ...
WebOct 2, 2014 · Software implementations of CHAID vary; typically, the user can specify a minimum significance of the chi-square test, a minimum cell size, and a maximum depth for the tree. The principal advantages of CHAID are its use of the chi-square test (which is familiar to most statisticians) and its ability to perform multiway splits. WebIn the CHAID algorithm proposed by Kass (Citation 1980), a chi-squared test (χ 2, chi-square statistic) is applied to determine the splitting condition. It is mainly used to calculate the degree of dependence between several variables–the larger the value calculated by χ 2 , the higher the degree of dependence and the probability value of ...
