Webcheck if the marginal distributions have changed for each feature (as explored by [25]); however, the marginal distribution would be easy for an adversary to simulate (e.g., by looping the sensor values from a previous day). Thus, marginal tests are not sufﬁcient for our purpose. Therefore, we propose to use conditional distribution tests. WebIn the right margin is the marginal distribution of X. In the bottom margin is the marginal distribution of Y. 3 Joint and Marginal Distributions (cont.) The rule for nding a marginal is simple.
