appropriate formulas to estimate the parameters of the PRF. We illustrated the OLS method with a fully worked-out numerical example as well as with several practical examples. Our next task is to find out how good the SRF obtained by OLS is as an estimator of the true PRF. We undertake this important task in Chapter 3. 3) The Two-Variable Model: Hypothesis Testing In Chapter 2 we showed how to estimate the parameters of the two-variable linear regression model. In this chapter we showed how the

perform very well and more work is needed to understand why this is the case. Of the remaining receivers‚ the ultra-tight receiver performed best‚ the estimator-based receiver performed second best and the standard receiver performed the worst. The ultra-tight receiver provided about 7 dB and 3 dB of sensitivity improvement over the standard and estimator-based receivers.

Introduction Recall also the consequences of heteroskedasticity for the OLS estimator: Under heteroskedasticity‚ the OLS estimator does not have the minimum variance among all the linear‚ unbiased estimators of β (i.e.‚ it is not BLUE) (Remember that the Gauss-Markov theorem states that homoskedasticity is a necessary condition for OLS to be BLUE) In particular‚ if the error term is heteroskedastic

Regression with a Binary Dependent Variable Binary Dependent Variables and the Linear Probability Model • • • Many of the decisions made by people are binary. What factors drive a person’s decision? This question leads to regression with a binary dependent variable. The binary choice problem is an example of models with limited dependent variables (see Appendix 9.3 for details). Note that the multiple regression model discussed earlier does not preclude a dependent variable from being binary

Market Prices Do Not Follow Random Walks: Evidence from a Simple Specification Test Andrew W. Lo A. Craig MacKinlay University of Pennsylvania In this article we test the random walk hypothesis for weekly stock market returns by comparing variance estimators derived from data sampled at different frequencies. The random walk model is strongly rejected for the entire sample period (19621985) and for all subperiod for a variety of aggregate returns indexes and size-sorted portofolios.
