Regression models are out there for a long time now, much longer before Machine Learning was a thing. Statisticians have been using these models to understand the relationship between variables even before the 1900s, when Sir Francis Galton (1885) introduced the idea.Fortunately, the theory has developed so much since then, and so have the computers and technology, up to the point that we can say that it is an easy (if not the easiest) model to create these days.However, do not be fooled by its easiness to implement. It…

Learn how to build MMMs for different countries the right wayPhoto by Annie Spratt on UnsplashImagine that you work in a marketing department and want to investigate if your advertising investments paid off. People who read my other articles know a way to do this: marketing mix modeling! This method is especially interesting because it also works in a cookieless world.I have also covered Bayesian marketing mix modeling, a way to get more robust models and uncertainty estimates for everything you forecast.The Bayesian…

Create a variety of data visualizations with hierarchal dataIndividual Images Cited BelowHierarchical data is a type of data structure where data points are linked to each other through parent-child relationships which form a tree structure. Hierarchal data is a common data structure so it is important to know how to visualize it. The visualization techniques used for this vary from other data structures because of the need to maintain the hierarchical relationship. This article will show six types of…

Essential guide to LSAN: Modeling Long-term dependencies and Short-term correlations with Hierarchical AttentionImage by Jukka Niittymaa from PixabayElectronic Health Records (EHR) are comprehensive historical health records that contain the symptoms of a patient when he/she visits a doctor. EHR data has a two-level hierarchical structure that consists of a set of time-ordered visits, and within each visit, there is a set of unordered diagnosis codes. The diagnosis codes can belong to the ICD-9 or ICD-10 format that…
