Predicting Academic Collaboration with Logistic Regression

My capstone project for my last year of undergrad has to do with Social Network Analysis of networks formed by co-authorship in research communities. Since I have a growing interest for machine learning I wanted to see if I could apply various machine learning methods to the networks in order to gather more insight into how they work. In this post I applied a logistic regression model in order to predict future collaboration, and it seemed to be quite accurate over the test set! I would love any feedback on the post, and I hope you enjoy!
