Values of a metric are provided at irregular intervals. A forgetting factor is calculated based on a difference between the intervals, and a statistical parameter is computed using the forgetting factor that causes different weights to be placed on the corresponding values of the metric, where the statistical parameter is part of an adaptive baseline.

Adaptive baseline based on metric values

To determine a seasonal effect in temporal data, for each of a plurality of candidate seasons, the following is performed. An interval is defined for the corresponding candidate season. The interval is divided into plural buckets containing respective sets of the temporal data, and statistical measures for corresponding buckets are computed. The computed statistical measures are used to compute a score for the corresponding candidate season. Scores computed for corresponding candidate seasons are used for identifying which of the candidate seasons represents the seasonal effect of the temporal data.
