These functionalities can be used for near real-time monitoring scenarios, such as fault detection. Earlier this year, we wrote about the value of exploratory data analysis and why you should care. Its analysis requires a different approach than, say, a classification or a regression data. Causal inference refers to the process of drawing a conclusion from a causal connection which is based on the conditions of the occurrence of an effect. Wiener-Granger causality (“G-causality”) is a statistical notion of causality applicable to time series data, whereby cause precedes, and helps predict, effect. MDS Courses. 4\\API\\Java.
