psi_auto_distance function

Cumulative Sum of Distances Between Consecutive Cases in a Time Series

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

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

Arguments

• x: (required, zoo object or matrix) univariate or multivariate time series with no NAs. 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".

Returns

numeric value

Examples

#distance metric
d <- "euclidean"

#simulate zoo time series
x <- zoo_simulate(
  name = "x",
  rows = 100,
  seasons = 2,
  seed = 1
)

#sum distance between consecutive samples
psi_auto_distance(
  x = x,
  distance = d
)
