The conditional expectation of x2 given x1 follows using the conditional probabilities, but note that there is one expectation for each outcome value of x1. 43) If independence holds for x1 = X1,i and x2 = X2,j, j = 1, ... 44) for j = 1, ... , m. 45) Introduction to Probability and Random Variables 29 If conditional expectations are being taken conditional on each of the values taken by the conditioning variable, then the notation can be simplified to E(x2 | x1), so that independence implies that E(x 2 | x1) = E(x2).

It is convenient to define a random variable that assigns +1 to H and 0 to T, giving rise to sequences comprising 1s and 0s. ) For a single trial and this assignment of x1, say, then E(x1) = 1p + 0q = p, and variance ␴2x1 = (1 – p)2 p + (0 – p)2 q = (1 – p)2 p + p2q = p(1 – p) using q = 1 – p. When the coin is tossed twice in sequence, we can construct a new random variable (which is clearly measurable) that counts the number of heads in the sequence and so maps ⍀2 into N (the set of nonnegative integers) say, S2 = x1 + x2, with sample space ⍀S,2 = {0, 1, 2} and probabilities {q2, 2pq, p2}; if p = q = ½, then these probabilities are {¼, ½, ¼}.

The second approach is adopted in more advanced treatments, where the emphasis is on a measure-theoretic approach; the interested reader may like to consult Davidson (1994, chapter 10) and Billingsley (1995, chapter 6). The idea taken here is to construct an interval set that shrinks to a single point in the limit; thus, let A = a ± ␧, where ␧ ≥ 0, which collapses to a in the limit as ␧ → 0+. 58d) The last line is just a matter of a shorthand notation. More substantively, the penultimate line follows from the mean value theorem for integrals and the continuity of f(X1) and f(X1, X2) in X1 for X1 ʦ A, see Mittelhammer (1996) for details.
