If you move an unsummarized numerical field into the Analyze field, you have a choice how to handle that scenario. While exploring the data and trying out different measures and dimensions in the decomposition tree, one may eventually find the hierarchy and dataset of interest using the drill-down approach and drill-through options. Power BI offers a category of visuals which are known as AI visuals. In next Blog, I will explained how to enable and disable AI Split and how to implement the relative and absolute concept. Segment 1 also contains approximately 2.2% of the data, so it represents an addressable portion of the population. . After each split, the decision tree also considers whether it has enough data points for this group to be representative enough to infer a pattern from or whether it's an anomaly in the data and not a real segment. Your explanatory factors have enough observations to generalize, but the visualization didn't find any meaningful correlations to report. The Microsoft Power BI Ultimate Decomposition Tree (Breakdown Tree) can display hierarchical Information with images, two measures and % calculation as well. I see an error that when 'Analyze' is not summarized, the analysis always runs at the row level of its parent table.
