SPLIT POINT-C

Description

C++ function that is called by splitPoint() to perform calculations.

Usage

splitPointC(s_, e_, D_, min_size_)

Arguments

s_	Index of the first obervation in a segment.
e_	Index of the last observation in a segment.
D_	A distance matrix.
min_size_	The minimum segment size.

Details

As with the splitPoint method, this method should not be calle by the user.

Value

Returns a vector. The first component is the most likely position of a change point. The second component is the distance between the segments created by this proposed change point.
