Before discussing the unique issues presented by time series data, we quickly review expectations and rst and second moments. 2 Expectations The expected value of x t is denoted by E(x t) and is the weighted average of possible realizations of x t, where the weights are the probabilities of each realization: E(x t) = XT t=1 x tp(x t) (1) This is a linear operator.
