The rtweet package makes it relatively simple to automate Twitter posts using a scheduling platform such as RStudio Connect or GitHub Actions. In this post, I work through the details using RStudio Connect.
The Cox Proportional Hazards model has so dominated survival analysis over the past forty years that I imagine quite a few people who regularly analyze survival data might assume that the Cox model, along with the Kaplan-Meier estimator and a few standard parametric models, encompass just about everything there is to say about the subject. This post introduces the counting process theory underlying survival analysis by examining a paper in which Bendix Carstensen demonstrates the equivalence of the Cox Portional Hazards model and a Poisson model.
We continue our series of posts looking into accounting and actuarial applications by showing how Sankey diagrams can be used to visualize cash flow information and hopefully improve communication with clients and decision makers who are not financial professionals.
