Drug safety data mining with a tree-based scan statistic

Assessing an entire collection of drug-event pairs is traditionally performed on a predefined level of granularity. It is unknown a priori whether a drug causes a very specific or a set of related adverse events, such as mitral valve disorders, all valve disorders, or different types of heart disease.

Data warehousing: What is a level of Granularity of a fact table?

The granularity is the lowest level of information stored in the fact table. The depth of data level is known as granularity. In date dimension the level could be year, month, quarter, period, week, day of granularity. The process consists of the following two steps: - Determining the dimensions that are to be included.

Event Granularity: Modelling events in event driven applications

These are questions of granularity, and in order to answer it, we had to understand the spectrum of granularity. When designing an event, you need to choose the right point on the spectrum. Too fine and the event isn't useful. Too coarse and they're not expressive. From our experience, there are really three ways you can get it wrong.
