Previously in this little series, we took a look at how we can describe our trended data by using the statistical Mean and Standard Deviation. While this works quite well for data that doesn’t change much over time, it is rather limited in regards to take trends into account. With this post, we are doing something about that issue by using Linear Regression techniques. At the end of this post, you will get an Analysis Workspace project like below, where we can judge trends in data and see changes over time: Let’s get our hands dirty! Limitations of Mean and Standard Deviation Before we start, I want to explain the problem outlined above a bit better. Please consider the following graph I generated with the Workspace from the previous post and some demo data: What we see is a clear trend in our data, since our daily Unique Visitors are […]

Predictive Regression Analysis – Statistics in Adobe Analytics
Adobe Analytics is awesome for analyzing historical data. Besides Segments, Drilldowns or Derived Metrics, it also offers some advanced statistical functions like Regression Analysis. Here are some examples for the different regression models that are available today: It would be really cool if we could use this functionality to predict the future with some regressive models! This is what this article is going to describe by using advanced calculated metrics. In the end, we want to have a graph like this, with the historical and future data in the same visualization: We will go through the whole process of generating a metric like shown above. If you just want the result, you can scroll down to the bottom of this article, where I show the complete metric. Let’s start! Statistics 101: Simple Linear Regression in Adobe Analytics To start things off, let’s remind ourselves what regression analysis does. To keep […]
