Homework 1 guidelines

These are a variety of comments I wrote on about 1/2 of the homeworks turned in last year. I allow resubmissions to fix such errors. But it would make both our lives easier if you followed these rules the first time around!
  1. Call your figures: figure 1, figure 2, etc.
  2. Give only one digit of accuracy for p-values. (.0003)
  3. Give SE's with ranges between 3 and 30. So .24, .04, not .395 or .01
  4. Give estimates to accuracy of SE: If SE = .25 => estimate 1.05. If SE = .3 estimate is 1.0.
  5. Make one point per graph. Draw as much attention to the single point you are trying to make in the graph. Anything that doesn't support your point should be removed. Be sure to tell the reader what this one point is in a caption! (So each graph should be highly edited to show off the key point graphically and then it should be captioned to tell the reader what to look for.)
  6. For the discussion section you want to guide the reader carefully. Avoid giving ALL the output. Just give what is necessary to make your case.
  7. The primary reason for putting figures at the end of a paper is convience to the author--not to the reader. So if you CAN put them in the text, that is always to be prefered. Now an appendix is a different matter altogether! It contains stuff that no one wants to read, but the author feels compelled to write.
  8. When looking at returns, there isn't much point in connecting the dots here since it doesn't "pass" through the intermediate points. Contrast this with looking stock prices--where it should pass through intromediate values. The way to see if it makes sense is to remove every other point, and connect the line between them. If that captures most of what happens, then it is a good thing to do.
  9. Anything worth measuring is worth discussing the meaning of. So if you bother to say that the beta is 1.05, then say what the beta means. If you give an intercept say what we are supposed to learn from it. (I.e. If the intercept were hugely positive--would we want to buy the stock or not?) You should of course mention the SEs, and hence they need to be interpreted also.
