WebOct 6, 2024 · The intervals between each record are very irregular. The first dataset has the following characteristics: Time period: 1 day. Number of samples: 2026. Max interval in seconds: 4377. Min interval in seconds: 0. Average interval in seconds: 41.17. 93% of intervals are under one minute, 85% are under 30 seconds and 80% are under 20 seconds. WebIrregular time series do not make the assumption that time series are equally spaced, but instead use the case id’s date and time values to compute the intervals between observed values. Models are constructed directly on the observed values with their observed spacing. Oracle time series analysis handles irregular time series.
