correlation

Hasn’t machine learning made the study of causation pointless? Well, not really.Many times, we are interested in a relationship of this kind: “if I do X, then Y will happen”, which is not the same as “if X happens, then Y will happen”. The difference is that in the first case, we’re actually forcing X to happen, while in the second case, X…

What is correlation? How can we compute correlation between to continuous variables? And what are the differences with covariance?Clearly, two persons who understood what is correlation.

Studying Machine Learning means taking the most interesting concepts coming from the most disparate fields (math, finance, biology, computer science, etc) with the aim of…

To delve into this alarming statistic, U.S.-trained Université de Montréal economist Karim Chalak and his coauthors did an econometric study of the rate of U.S. gun ownership and the associated risk of death, and found it to be much higher than previously thought.…
