Web3.1 Expectation The mean, expected value, or expectation of a random variable X is writ-ten as E(X) or µ X. If we observe N random values of X, then the mean of the N values will be approximately equal to E(X) for large N. The expectation is defined differently for continuous and discrete random variables. WebMar 12, 2024 · The marginal means of gender are simply the means of each level of gender averaged across each level of studying technique. For example, the marginal mean exam score of males is calculated as: Marginal Mean of Males: (79.5 + 88.7 + 89.2) / 3 = 85.8 Similarly, the marginal mean exam score of females is calculated as:

WebAveraging means calculating the marginal expectation E over the features in set C, which is the integral over the predictions weighted by the probability distribution. Sounds fancy, but to calculate the expected value over the marginal distribution, we simply take all our data instances, force them to have a certain grid value for the features ...
