sol.idetect_seq {breakfast} | R Documentation |
This function uses the Isolate-Detect method in its original sequential way in order to create the solution path. It is developed to be used with the thresholding model selection rule.
sol.idetect_seq(x, points = 3)
x |
A numeric vector containing the data to be processed |
points |
A positive integer with default value equal to 3. It defines the distance between two consecutive end- or start-points of the right- or left-expanding intervals, as described in the Isolate-Detect methodology. |
The Isolate-Detect method and its algorithm is described in "Detecting multiple generalized change-points by isolating single ones", A. Anastasiou & P. Fryzlewicz (2021), Metrika, https://doi.org/10.1007/s00184-021-00821-6.
