## k-Means Cluster Analysis – Machine Learning

Machine Learning Data Analysis This is the last lesson of the fourth course of my Data Analysis and Interpretation Specialization by Wesleyan University through Coursera. If you have been following along with my work, you will know that I am interested in the relationship between urbanization and economic development and am posing the general question of whether urbanization drives economic growth? For this assignment, the goal is to run a k-Means Cluster Analysis using my variables: Urban Population, Urban Population Growth, GDP Growth, Population Growth, Employment Rate, and Energy Use per Capita in 2007. Here, GDP per Capita in 2007 is used as the validation variable. I am trying to identify if there are clusters of characteristics that associate with certain values of GDP per Capita based on national data from 2007. As before, the data is split into 70% training data and 30% test data. However, the k-means cluster analysis will only be run on the training data set. The Elbow Curve Graph shows that 2, 3, and 4 clusters could be interpreted, though it is …
