Esther Williams and John Gottman describe a complete set of programs they have written in Fortran IV to enable even beginners to use all the techniques presented in John Gottman's Time-Series Analysis: A Comprehensive Introduction for Social Scientists. There are three packages, available on IBM card source desks from the authors, for (1) time and frequency domain model fitting, including detecting cycles, (2) forecasting and interrupted time-series analysis, and (3) multivariate time-series analysis, in both time and frequency domains. The packages have been tested for portability. Modification specific computers are noted in the guide.
