- Is this a homework problem or will the solution to this
- statistical issue help GM build better cars? The net has
- informal prohibitions against providing answers to homework
- problems. The problem you raise is a very standard homework
- assignment in undergraduate statistics classes. When I did it as
- a homework problem many years ago I remember that it was a bit
- easier to do it as W = 1/(1+(m/n)F). It won't help you solve it,
- but a useful insight is that W is often known as R^2. Good luck!
