Interface: TemporalTrendSummary

Defined in: src/types/temporal.ts:461

A closed-form linear-trend summary.

Remarks

Present only for the trend operator. slopePerMs and intercept are the least-squares fit over event-time in milliseconds, so a per-day slope is slopePerMs * 86_400_000.

Example

if (series.trend) {
  const perDay = series.trend.slopePerMs * 86_400_000;
  console.log(`drift: ${perDay}/day over ${series.trend.n} observations`);
}
