RE: For class on 3/25

Hope you all had a good weekend and you did not bet the rent money on the Duke game. But it WAS a great game.

NEW NOTE FILE
I have put up a new note file -- NOT9908. Please download it and read it at least once, along with chapter 3 in Hamilton. We are going to need to start talking about multiple correlation and partial correlation. With luck we will be able to start that conversation on Thursday 3/25.

NEW LAB
In addition, I have put up a lab file, with some command syntax stuff in it. Please download and peruse, so that when we get into the lab you at least have had a gander at the material. It also indicates what will be happening for your homework next week. In the lab we will be running BOTH an ecological regression, and looking at residuals, and an individual-level regression, and looking at residuals. Be sure to bring the latest copies of both your ecological data file and your individual data file.

QUIZ
On the quiz that is coming up: you need to know all the material that we have covered in the notes and in Hamilton on simple regression. These topics include:
b
beta (even though we have not had a chance to talk about this in class, I think it is pretty clear in Hamilton and in NOT9905).
R squared
constant
significance testing of b and R squared
assumptions about error terms, and what are predicted and residual scores

CALLS
Call me if you have questions. However, I will not be taking calls the night before class.

TRYING TO RUN DOWNLOADED SYNTAX FILES
I think the problem with trying to run command files last week was that browsers do not recognize spaces consistently at the beginning of a command line. Sometimes they overlook them. And this is important for SPSS because SUBcommands are INDENTED following non-indented main command lines. I have tried to fix this in the file, but you may need to fiddle around some with this yourself, if you choose to submit this file as a set of commands.
Since the lab file has the commands in it I have uploaded it both as an html file and the commands separately as a txt file.
