Detect the number and locations of change points based on minimizing within segment quadratic loss with restriction of prior ranges that contaion change points.
1 | PriorRangeOrderKmeans(x, prior_range_x, num_init = NULL)
|
x |
The data to find change points. |
prior_range_x |
The prior ranges that contain change points. |
num_init |
The number of repetition times, in order to avoid local minimal. Default is squared root of number of observations. Must be integer. |
The K prior ranges contain K change points, each prior range contaions one change point.
num_change_point |
optimal number of change points. |
change_point |
location of change points. |
