Time Series: Yale Enrolment

  • Francis John Anscombe
Part of the Springer Series in Statistics book series (SSS)


As an example of examination of a time series, let us consider the enrolment of students at Yale University. Information concerning the numbers of students enrolled in the various schools and programs can be obtained for each academic year from 1796/97 onwards. The University was founded in 1701. For most years before 1796 the enrolment is not known directly, though Welch and Camp (1899) made estimates from the numbers of degrees awarded. For present purposes we shall start at 1796, and use the counts of total enrolment listed in Figure B:2, a time series of length 180.
