ILD types

ILD types

This is the landing page for everything related to different types of intensive longitudinal data (ILD).

For instance, sampling faster and more frequently allows you to see more detail in the fluctuations of a process over time; sampling for a longer period, allows you to see whether the process is characterized by slow changes over time; and sampling multiple cases allows you to see whether the process is characterized by individual differences.

Below we have specified multiple articles where you can read more about important aspects to consider when designing your sampling scheme.

ILD collection methods and terminology

There are many ways to collect ILD and there is a lot of terminology that partly overlaps.

Choosing between ILD collection methods

To decide what is the best way to measure a process, it can help to consider the pros and cons of various methods.

[Ecological momentary assessment versus ecological retrospective assessment]
[Active versus passive sensing]

Selecting a subset of occasions

The timing of your measurement occasions is essential to what patterns you may capture from your process of interest.
