Write a review on visualization methods used in the presentation by the speaker and post on own GitHub website.

The colloquium was very challenging for me and difficult to understand and interpret. Most of the concepts discussed by the professor were new to me and for some of them I eve had to refer Google and understand the terminologies. Having this in my first semester is sometimes a bit overwhelming as I am yet to learn a lot and experiment with R studio, shiny and the visualization aspect of it. I have normally dealt with stationary data points and visualizations like bar plot, scatter plot etc which are pretty basic. This would be the first time I am working with time series data and initially it took a toll on me as it was difficult to interpret and work with. Dr. Patrick Brandt discussed multiple categories or “types” or models. These models were specific to “Statistics & Time Series for Policy Intervention & Change Identification”, which was the topic of the colloquium presentation. There were four types of models or visualizations that Dr. Brandt described: Type 0 (Basic Time Series), Type 1 (Binary Segmentation), Type 2 (Regularization and Fused Lasso), and Type 3 (Bayesian methods).

My version of the plots :
