Validating analysis time window

For any given window with a specified time length, some actors exhibit higher levels of network activity than others; for example, an actor (Actor 1) in a longitudinal network might create only one new tie in a window, while another actor (Actor 2) in the same longitudinal network might forge five new ties in the same window.

In a longitudinal study on smoking behaviour, for example, Collins and Graham found a positive correlation between smoking and peer smoking; however, the strength of the relationship was found to decrease as the window size increased.All time-stamped network activities within each window are aggregated when conducting a longitudinal network data analysis.Window size selection is considered to be central to the design of any longitudinal research study; however, researchers often overlook this component.In the present study, we hypothesise that the selected window size of a longitudinal network should ensure that the actors of that network exhibit a minimal level of variance in their positional dynamicity values.Simultaneously, the study shows that basic social network measures (e.g., centrality measures) can successfully delineate an actor’s positional dynamicity in longitudinal networks.

The design of a longitudinal study involves the selection of a window size before or after data collection.
