Types of change

This is the landing page for topics related to different types changes that may characterize your process of interest.

A process varies over time. We can characterize this variation by lasting changes, reversible changes, or no changes (i.e., mere fluctuations).

Below we have specified multiple articles where you can read more about types of change.

Think more about types of change

Lasting changes

Models that account for changes in processes that are lasting, for instance, processes that are determined by development or decline.

  • [Growth curves]
  • [Change point analysis]
Reversible changes

Models that account for changes in processes that are reversible, for instance, when a process is characterized by switches back and forth between different regimes.

  • [Sine wave]
  • [Threshold autoregressive models]
  • [Regime switching models]
  • [Time-varying models]
No changes

Models that account for fluctuations in the absence of structural changes in processes, for instance, a self-regulation process.

  • [Autoregressive model]
  • [Autoregressive moving average model]
  • [Unit root]
