Chimerge in python
WebJul 24, 2024 · Here the null hypothesis is: the discreet random variable is not significantly different from the expected distribution. Unlike chi2_contingency, chisquare returns chi-square statistic and the p-value. To look at the expected distribution (by the algorithm) call ‘expected_freq’ from ‘scipy.stats’ and pass the observed value table in it.

WebAbstract: Many classification algorithms require that the training data contain only discrete attributes. To use such an algorithm when there are numeric attributes, all numeric values must first be converted into discrete values-a process called discretization. This paper describes ChiMerge, a general, robust algorithm that uses the x2 ... WebChiMerge Algorithm uses Chi-squared statistic to discretize attributes (numeric). In toad, we firstly transform Char/Object attributes to numeric with WOE function. The Algorithm is clear in paper (i.e. ChiMerge Algorithm …
