- I have a variable that I think is a very good predictor of my good/bad
- outcome measure. However, it is so good (and I have so few cases)
- that all of the good outcome cases measure in the "good" category
- of the predictor variable ... that is the situation is like
- this (where the numbers are the N in each cell) :
-
-
- Outcome Variable
- Predictor var bad good
- low 143 28
- high 25 0
-
-
- What I really want is to compute odds ratio - but I don't know how to handle
- the 0 cell .....

- On a related issue, I have another variable in the same model that is
- "the number of people living in the home" ... I want to be able to say
- something like: "Living with 4 or more people puts a child at risk of xxx"
- Is there a standard way to determine the cut point? I know I could leave it
- continuous but in the first place I don't think it is linear and in the second
- I want to know when the risk starts not just that more is worse....
-
- Thanks in advance,
