👉 Non-correlating is a concept in probability theory that refers to two random variables X and Y being independent, but not necessarily identically distributed. This means that if we observe X and Y independently, then their joint distribution cannot be described solely by the marginal distributions of X and Y. In other words, while one variable can be predicted based on the other, there is no direct relationship between them. If we observed an observation from both variables, it would not necessarily mean that they are independent.
