Sample mean is the estimate for population mean, so we have the following interpre-tation for the estimated coefficients in (2) ˆ 0 = ¯yD=0 (8) ˆ 1 = ¯yD=1 ¯yD=0 (9) where ¯yD=0 denotes the average Y in the sub-sample for which D = 0; y¯D=1 denotes the average Y in the sub-sample for which D = 1: Equation (2) provides a simple way to carry out a comparison of means test (or …

Matrix Algebra for OLS Estimator - Miami University

Independent Variables • Suppose there are k independent variables and a constant term. In the spreadsheet there are k +1 columns and n rows. • Mathematically that spreadsheet corresponds to an n × (k +1) matrix, denoted by X : X = 1 x11::: x1k 1 x21::: x2k 1 xn1::: xnk where xij is the i-th observation of the j-th independent variable. 4

Lecture: IV and 2SLS Estimators (Wooldridge’s book chapter 15)

It is straightforward to account for heteroskedasticity. The robust variance-covariance matrix for bˆ 2SLS allowing for heteroskedasticity is robust var-cov(bˆ 2SLS)= X 0PX 1 X PWPX X PX 1 where W = E(UU0): To estimate the meat in the middle of that sandwich, using X0PWbPX = Xb0WbXb= n å i=1 uˆ2 i bx ibx 0 i where ˆu denotes the 2SLS ...

Lecture 5a: ARCH Models - Miami University

Consider the first order autoregressive conditional heteroskedasticity (ARCH) process rt = σtet (5) et ∼ white noise(0, 1) (6) σt = √ ω + α1r2 t 1 (7) where rt is the return, and is assumed here to be an ARCH(1) process. et is a white noise with zero mean and variance of one. et may or may not follow normal distribution. 7

Lecture 8a: Spurious Regression

The traditional statistical theory holds when we run regression using (weakly or covariance) stationary variables. For example, when we regress one stationary series onto another stationary series, the coefficient will be close to zero and insignificant if the two series are independent.

Lecture 7a: Vector Autoregression (VAR)

The goal of structural VAR analysis is to obtain B, which is not unique (for a bivariate system Ω has 3 unique elements, while B has 4 elements to be determined). 3. The Sims (1980) structural VAR imposes the restriction that B ... Instead, we simulate the impulse response for VAR(p) 28.
