A time series is a data set wher successive data items were refer to the same phenomenon at different potns in time. These may be sampled uniformly, for example, measuring the air temperature every morning at 6am, or spordically, for example blood-pressure reading when a patient happens to have been with the doctor for various other reasons. The data may also be homgenuous, each item of identicsl form, or heterogeneous , for example wher a heakth record mayinclude all sorts of different tests at different times. There are various statisticla and AI methods for time series analysis although, in general, periodic homogeneous data is dealt with most well.
