Assignment 2
1. Following the last assignment, the following shows a scatterplot of "experience" against
"education" with a regression line superimposed. We assume the following relationship
between the two variables: experience; = Bo + Bjeducation; + €;, where e; * N(0, o2).
Scaterpiot of eperience versus education with regression line supetimposed
Education
(1) What is the independent variable? What does the independent variable correspond to in
the graph? What is the dependent variable? What does the dependent variable correspond
to in the graph?
(2) What are Bo and 31? What do Bo and B1 correspond to in the graph? (Hint: Do we
know Bo and B1?) Denote Bo and B1 as our ordinary least squares (OLS) estimates of Bo and
B1. What do Bo and B1 correspond to in the graph? What are the relationships between
Bo and Bo and that bewteen B1 and B1? Does Bo = Bo or B1 = B1? Are there any methods
other than OLS we can use to estimate Bo and B1? Will all the methods produce the same
estimates of Bo and 3?
