1887 F. H. Bradley in Mind 12 579 I ought perhaps to begin by attempting to explain how it is possible to reproduce a time-series at all.

1920 S. Alexander Space, Time & Deity viii. 234 Occurring in the one Space, these time-series are connected in Time by the temporal relations between their respective places.

1944 C. S. Lewis Beyond Personality iii. 21 God, I believe, does not live in a Time-series at all. His life is not dribbled out moment by moment like ours.

1994 R. Swinburne Christian God iv. 83 All such events of which we learn are linked to us by a chain of causes and effects and are thus located within our time series.

2. A series of values of some quantity obtained at successive times (often with equal intervals between them). time-series analysis n. the statistical analysis of such series.

1928 Jrnl. Amer. Statist. Assoc. 23 407 The inferential possibilities of time series analysis are contingent upon segregating from the specific historical the repeatable, recurrent element.

1979 J. Hicks Causality in Econ. v. 64 There are two kinds of time-series, with different kinds of time reference. In one of them each item relates to a point of time, in the other to a period.
