[scikit-learn/sklearn, pandas] Plot percent of variance explained for KMeans (Elbow Method)

eblow.py

import pandas as pd
import matplotlib.pyplot as plt
import seaborn
from sklearn.cluster import KMeans
import numpy as np
from scipy.spatial.distance import cdist, pdist

def elbow(df, n):
    kMeansVar = [KMeans(n_clusters=k).fit(df.values) for k in range(1, n)]
    centroids = [X.cluster_centers_ for X in kMeansVar]
    k_euclid = [cdist(df.values, cent) for cent in centroids]
    dist = [np.min(ke, axis=1) for ke in k_euclid]
    wcss = [sum(d**2) for d in dist]
    tss = sum(pdist(df.values)**2)/df.values.shape[0]
    bss = tss - wcss
    plt.plot(bss)
    plt.show()

Did you purposely spell this eblow instead of elbow?

@ericbf nope, didn't notice :). Thanks
