What are design confounds?
Confounding: A confounding design is one where some treatment effects (main or interactions) are estimated by the same linear combination of the experimental observations as some blocking effects. Design: A set of experimental runs which allows you to fit a particular model and estimate your desired effects.
What is a covariation and how is it used?
Covariance is a statistical tool that is used to determine the relationship between the movement of two asset prices. When two stocks tend to move together, they are seen as having a positive covariance; when they move inversely, the covariance is negative.
