hdcd(x, delta = 0.1, gamma = 0, lambda = NULL, method = NULL,
  optimizer = "line_search", segmentation = "BS",
  control = hdcd_control())

Arguments

x

A matrix with observations in rows

delta

Minimal relative segment length, defaults to 0.1

gamma

Minimal required gain to split in the Binary Segmentation Procedure. Defaults to 0.

lambda

Tuning parameter passed to the method.

method

Method to be applied for change point detection. One of glassocd, RFcd, kNNcd, custom_classifier, custom_gain_function, custom_best_split_function.

optimizer

Optimization method to be used to find an (approximate) of the maximum of the gain function. One of line_search for BS or similar, section_search for OBS or similar or two_step_search.

segmentation

Segmentation method to be used. One of BS, SBS or WBS.

control

Control parameter as returned by hdcd_control
