tidyclust (version 0.2.4)

sse_total: Compute the total sum of squares

Description

Compute the total sum of squares

Usage

sse_total(object, ...)
# S3 method for cluster_spec
sse_total(object, ...)
# S3 method for cluster_fit
sse_total(object, new_data = NULL, dist_fun = NULL, ...)
# S3 method for workflow
sse_total(object, new_data = NULL, dist_fun = NULL, ...)
sse_total_vec(
  object,
  new_data = NULL,
  dist_fun = function(x, y) {
     philentropy::dist_many_many(x, y, method =
    "euclidean")
 },
  ...
)

Value

A tibble with 3 columns; .metric, .estimator, and .estimate.

Arguments

object

A fitted kmeans tidyclust model

...

Other arguments passed to methods.

new_data

A dataset to predict on. If NULL, uses trained clustering.

dist_fun

A function for calculating distances to centroids. Defaults to Euclidean distance on processed data.
