Lecture 1. Random vectors and multivariate normal …

1.5 Quadratic forms in normal random vectors Let X˘N p( ;). A quadratic form in Xis a random variable of the form Y = X0AX= Xp i=1 Xp j=1 X ia ijX j; where A is a p psymmetric matrix and X i is the ith element of X. We are interested in the distribution of quadratic forms and the conditions under which two quadratic forms are independent ...

Lecture 2. The Wishart distribution

n] is the p nmatrix of de-meaned random vectors. We claim the following: 1. Y j are normally distributed. 2. E(Y jY0 k) = ˆ; if j= k; 0; if j6=k. 3. P n i=1 Y iY 0= P n i=1 X~ i X~ i: 4. Y 1Y0 1 = n(X )(X )0: The facts 1 and 2 show the independence, while facts 3 and 4 give the distribution of S. Next lecture is on the inference about the ...

PAIR OF LINEAR EQUATIONS IN TWO VARIABLES

(A) Main Concepts and Results • Two linear equations in the same two variables are said to form a pair of linear equations in two variables. • The most general form of a pair of linear equations is a 1 x + b 1 y + c 1 = 0 a 2 x + b 2 y + c 2 = 0, where a 1, a 2, b 1, b 2, c 1,c 2 are real numbers, such that 2 2 22 ab a b11 22+ ≠ +≠0, 0. • A pair of linear equations is consistent if ...

ANALYSIS OF CONTINUOUS VARIABLES COMPARING …

ANALYSIS OF CONTINUOUS VARIABLES / 31 CHAPTER SIX ANALYSIS OF CONTINUOUS VARIABLES: COMPARING MEANS In the last chapter, we addressed the analysis of discrete variables. Much of the statistical analysis in medical research, however, involves the analysis of continuous variables (such as cardiac output, blood pressure, and heart rate) which can assume an …
