Expected Value, Variance and Covariance
utstat.toronto.eduExpected ValueVarianceCovariance Conditional Expectation The idea Consider jointly distributed random variables Xand Y. For each possible value of X, there is a conditional distribution of Y. Each conditional distribution has an expected value (sub-population mean). If you could estimate E(YjX= x), it would be a good way to predict Y from X.
