Notes on Probability
Set books The notes cover only material in the Probability I course. The text-books listed below will be useful for other courses on probability and statistics. You need at most one of the three textbooks listed below, but you will need the statistical tables. • Probability and Statistics for Engineering and the Sciences by Jay L. De-

Notes on Linear Algebra - Queen Mary University of London
www.maths.qmul.ac.ukLinear algebra has two aspects. Abstractly, it is the study of vector spaces over fields, and their linear maps and bilinear forms. Concretely, it is matrix theory: matrices occur in all parts of mathematics and its applications, and everyone work-ing in the mathematical sciences and related areas needs to be able to diagonalise
6.2 ACF and PACF of ARMA(p,q)
www.maths.qmul.ac.uk6.2.2 PACF of ARMA(p,q) We have seen earlier that the autocorrelation function of MA(q) models is zero for all lags greater than qas these are q-correlated processes. Hence, the ACF is a good indication of the order of the process. However AR(p) and ARMA(p,q) pro-

www.columbia.edu1.3 Examples of well-known distributions Discrete case 1. Bernoulli distribution with success probability p: With 0 < p < 1 a constant, X has p.m.f. p(k) = P(X = k) given by p(1) = p, p(0) = 1−p, p(k) = 0, otherwise. Thus X only takes on the values 1 (success) or 0 (failure). A simple computation yields E(X) = p Var(X) = p(1−p) M(s) = pes ...
