Partitioning cluster analysis: Quick start guide - Unsupervised Machine Learning and

Clustering is a data exploratory technique used for discovering groups or pattern in a dataset. There are two standard clustering strategies: partitioning methods and hierarchical clustering.
      
This article describes the most well-known and commonly used partitioning algorithms including:   
    
- K-means clustering (MacQueen, 1967), in which, each cluster is represented by the center or means of the data points belonging to the cluster.
K-medoids clustering or PAM (Partitioning Around Medoids, Kaufman & Rousseeuw, 1990), in which, each cluster is represented by one of the objects in the cluster. We'll describe also a variant of PAM named CLARA (Clustering Large Applications) which is used for analyzing large data sets.
   
For each of these methods, we provide:  
   
- the basic idea and the key mathematical concepts
- the clustering algorithm and implementation in R software
- R lab sections with many examples for computing clustering methods and visualizing the outputs

Great article on the inequality of income, the overproportional gains made out of capital and why the vast majority of us wont get a pay raise http://www.vox.com/2015/1/8/7511281/labor-share-income
The labor share of income is falling. Here are our best guesses as to why.

If you are aiming towards building an impeccable predictive model, then nothing but Data Exploration can be highly rewarding. Get accustomed to Data Exploration before Algorithms. And to do this, we present to you a cheatsheet of 11-step to Data Exploration in R explained with codes. http://buff.ly/1VCroOz
