Cumulative Sum of Distances Between Consecutive Cases in a Time Series — psi_auto_distance • distantia

Demonstration function to compute the sum of distances between consecutive cases in a time series.

Usage

psi_auto_distance(x = NULL, path = NULL, distance = "euclidean")

Arguments

x: (required, zoo object or matrix) univariate or multivariate time series with no NAs. Default: NULL
path: (optional, data frame) result of psi_cost_path_ignore_blocks(), only required if blocks in the least cost path were ignored. Default: NULL
distance: (optional, character vector) name or abbreviation of the distance method. Valid values are in the columns "names" and "abbreviation" of the dataset distances. Default: "euclidean".

Value
