Summary of Irizarry Ch. 15

Estadística para las Ciencias Sociales

This report corresponds to the milestone for the final project of the Data Science Specialization at Johns Hopkins University. My objective is to demonstrate that the text data has been successfully downloaded, loaded, and pre-processed, and to conduct an exploratory analysis of the corpus. In this report, I focus on three datasets—Twitter, News, and Blogs—and provide summary statistics, data cleaning steps, and visualizations that reveal the underlying structure of the data. Finally, I outline the plan for building a predictive text model and developing an interactive Shiny application.
