On the first article, we saw a quick-and-dirty method to predict disk space exhaustion when the usage pattern is rigorously linear. We did that by importing our data into R and making a linear regression. In this article we will see the problems with that method, and deploy a more robust solution. Besides robustness, we will also see how we can generate...
