| Name | Type | Description | Notes |
|---|---|---|---|
| metrics | \TalonOne\Client\Model\ExperimentSegmentInsightMetric[] | Segment insights grouped by metric. This array always contains exactly three metric objects. Each metric includes a segments array, which is empty if no significant results were found. The metrics array itself is empty if the `reason` property is populated. | |
| totalSegmentsTested | int | Total number of segment-metric combinations that were tested for statistical significance. | |
| dimensionsTested | int | Number of segmentation dimensions that had sufficient data variance to test. Dimensions where all sessions fall into a single bucket are excluded. | |
| reason | string | Empty string when segment insights are available. Contains a reason code when insights could not be computed (e.g., "insufficient_data" when the experiment has fewer than 100 sessions per variant). |
