The strategy is to find a statistical model that accounts for a discrete dependent variable. Estimating that model then yields parameter estimates... http://www.econ-courses.com/parke/170fall2005/archives/2005/12/logitprobit.html http://www.econ-courses.com/parke/170fall2005/archives/2005/12/logitprobit.html Thu, 08 Dec 2005 21:32:10 -0500 If the regressors are not exogenous, we need to worry about simultaneity bias. That is, the parameters estimates are inconsistent, which means that they are biased and the bias does not go away in large samples. A basic supply and... http://www.econ-courses.com/parke/170fall2005/archives/2005/12/simultaneity.html http://www.econ-courses.com/parke/170fall2005/archives/2005/12/simultaneity.html Tue, 06 Dec 2005 23:20:48 -0500 http://www.econ-courses.com/parke/170fall2005/archives/2005/12/heteroskedastic.html http://www.econ-courses.com/parke/170fall2005/archives/2005/12/heteroskedastic.html Thu, 01 Dec 2005 23:06:31 -0500 http://www.econ-courses.com/parke/170fall2005/archives/2005/11/review_of_sprin.html http://www.econ-courses.com/parke/170fall2005/archives/2005/11/review_of_sprin.html Tue, 15 Nov 2005 22:54:25 -0500 Forecasting.... http://www.econ-courses.com/parke/170fall2005/archives/2005/11/serially_correl_2.html http://www.econ-courses.com/parke/170fall2005/archives/2005/11/serially_correl_2.html Thu, 10 Nov 2005 22:49:15 -0500 The Wall Street Journal "C" Section (Money and Investing) basically gives a daily discussion of the choice among stocks, bonds, and cash.
