Abstract

Systems and methods are provided for handling time-stamped data. The one or more GUIs may be used to define properties of an event and to associate the event with time-stamped data. The properties of the event defined using the one or more GUIs may include one or more statistical properties that indicate how the event statistically affects the time-stamped data. A time series analysis program may use the time-stamped data and the associated event to generate a mathematical model.

Claims

1. One or more graphical user interfaces for use with a time series analysis program, comprising:

one or more data association input regions for associating an event with stored time series data;

one or more event defining user input regions for defining properties of the event including one or more statistical properties of the event that indicate how the event statistically affects the stored time series data;

wherein the time series analysis program uses the time series data and the associated event to generate a time series model.

2. The one or more graphical user interfaces of claim 1, further comprising:

a display region for displaying the event and the time series data.

3. The one or more graphical user interfaces of claim 2, wherein the display region may be used to graphically define properties of the event.

4. The one or more graphical user interfaces of claim 1, wherein the one or more event defining user input regions include a region for inputting a name of the event.

5. The one or more graphical user interfaces of claim 1, wherein the one or more event defining user input regions include a region for inputting an event type that defines the statistical properties of the event.

6. The one or more graphical user interfaces of claim 5, wherein the event type may be selected from a list of predefined event types.

7. The one or more graphical user interfaces of claim 6, wherein the list of predefined event types includes a pulse type event, a level shift type event, a ramp type event, and a decay type event.

8. The one or more graphical user interfaces of claim 5, wherein the region for inputting an event type includes a field for inputting a user-defined event type.

9. The one or more graphical user interfaces of claim 8, wherein the one or more event defining user input regions includes a region defining a combination event type from a plurality of predefined event types.

10. The one or more graphical user interfaces of claim 9, wherein the plurality of predefined event types includes two or more of a pulse type event, a level shift type event, a ramp type event, and a decay type event.

11. The one or more graphical user interfaces of claim 1, wherein the one or more event defining user input regions include a region for inputting a starting time of the event.

12. The one or more graphical user interfaces of claim 1, wherein the one or more event defining user input regions include a region for inputting a duration of the event.

13. The one or more graphical user interfaces of claim 1, wherein the one or more event defining user input regions include a region for defining recurrence of the event.

14. The one or more graphical user interfaces of claim 1, wherein the one or more data association input regions include a region for selecting the stored time series data from a list of available time series.

15. The one or more graphical user interfaces of claim 1, wherein the one or more data association input regions may be used to associate the event with a plurality of stored time series.

16. The one or more graphical user interfaces of claim 1, wherein the time series analysis program is configured to generate a forecast using the time series model.

18. A system for generating a time series model from stored time series data, comprising:

software instructions for generating one or more graphical user interfaces that are operable to define properties of an event and to associate the event with the stored time series data;

wherein the properties of the event include one or more statistical properties of the event that indicate how the event statistically affects the stored time series data;

a time series analysis program configured to use the stored time series data and the associated event to generate the time series model.

19. The system of claim 18, wherein the one or more graphical user interfaces include a display region for displaying the event and the time series data.

20. The system of claim 19, wherein the display region may be used to graphically define properties of the event.

21. The system of claim 18, wherein the one or more graphical user interfaces include a region for inputting a name of the event.

22. The system of claim 18, wherein the one or more graphical user interfaces include a region for inputting an event type that defines the statistical properties of the event.

23. The system of claim 18, wherein the time series analysis program is configured to generate a forecast using the time series model.

24. The system of claim 18, wherein the time series model is used for process control.
