POL242Y5 Lecture Notes - Lecture 17: Time Series, Dependent And Independent Variables
Document Summary
Test next week: chapter 11 (will be on test: do not need to know the calculations but should know what stuff means, should know trends, autocorrelation etc, reading will be on the test. Four categories: specialist, major, minor, other (reference category so leaving it out) Assignment mark = specialist + major + minor + intercept. Y =8x1 + 12x2 + 7x3 + 60. If difference is the same there is no effect. What is the effect of a one unit increase of x, on y? . What is the effect of age depends on the effect of education! Do not ever right interaction depends on circumstances, In the two variables one depends on the other, Y = b1x1 +b2x2 +b3 (x1x2) + a. Income = education + age + (education*age) + intercept. Main effect of age (x2) main effect of education and age (x1x2) Predicted value formula: war deaths = conflict + peacekeepers + intercept.
