The count of features with at least one location statistic that could not be calculated is displayed. Local statistics can fail to calculate for a feature for various reasons, including the following:
- The feature has no neighbors.
- All neighbors have zero weights or null values.
- Skewness and quantile imbalance require at least two unique values in neighbor values.
- Quantile imbalance can fail to calculate if the interquartile range of neighbor values is zero.
No action is required, but you may want to investigate why these features could not calculate at least one local statistic.
