updateDistance: UPDATE DISTANCE

Description

Update the distance between the newly created segment and the other segments.

Usage

updateDistance(i,j,K,ret)

Arguments

i

The segment that makes up the left portion of the new segment.

j

The segment that makes up the right portion of the new segment.

K

Integer indicating the progress of the agglomerative process.

ret

A list with 'gof', 'list', 'N', 'sizes', 'right', 'left', 'open', 'D', and 'lm' components.

Value

• Returns a list with the following components.
• gof
  Vector showing the progression of the goodness of fit statistic.
• list
  Matrix showing the progression of the set of change points.
• N
  Number of initial segments.
• sizes
  Sizes of each segment during the agglomerative process.
• right
  Vector containing indices of the right adjacent segments.
• left
  Vector containing indices of the left adjacent segments.
• open
  Vector indicating if a segment has been merged.
• D
  Matrix of distances between segments.
• lm
  Vector containing indices of the starting point of a segment.

Details

This method is called by the e.agglomerative method, and should not be called by the user.
