sse_total: Compute the total sum of squares

In tidyclust: A Common API to Clustering

Compute the total sum of squares

Description

Compute the total sum of squares

Usage

sse_total(object, ...)

## S3 method for class 'cluster_spec'
sse_total(object, ...)

## S3 method for class 'cluster_fit'
sse_total(object, new_data = NULL, dist_fun = NULL, ...)

## S3 method for class 'workflow'
sse_total(object, new_data = NULL, dist_fun = NULL, ...)

sse_total_vec(object, new_data = NULL, dist_fun = Rfast::dista, ...)

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.

Value

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