The RtChangePointDetection function detects change points in a stochastic process or time series, using real-time change-point detection, implemented with these algorithms:

  • Search algorithm: sliding window
  • Segmentation algorithm: normal distribution

Use this function when the input data cannot be stored in memory, or when the application requires a real-time response. If the input data can be stored in memory and the application does not require a real-time response, use the function ChangePointDetection.
