# Interface StageDwellStatistics

Statistics for a single `(procedureType, stage)` pair.

All numbers are in days. `sampleSize` exposes how many observations the statistics were derived from — callers should treat low-sample cells as less reliable and may degrade `forecastBasis` to `INSUFFICIENT_DATA`.

## Properties

### medianDwellDays

medianDwellDays: number

Median number of days a procedure dwells at this stage before moving on.

- Defined in utils/lifecycleStatistics.ts:60

### medianRemainingDays

medianRemainingDays: number

Median number of days remaining from this stage until the final event of the same procedure. Used as the forecasting baseline.

- Defined in utils/lifecycleStatistics.ts:67

### p95DwellDays

p95DwellDays: number

95th-percentile dwell — exceeding this is the bottleneck threshold.

- Defined in utils/lifecycleStatistics.ts:62

### sampleSize

sampleSize: number

Number of observations contributing to the dwell distribution.
