Paul C asked:


I want to find out if there’s a correlation between a number of events (column one) noted 1, 2 , 3, 4 (as took place only once, twice etc) and a certain consequence (let us say death) having the number of subjects that went through that events (once or twice etc) as the second column and the number of subjects that suffered the consequence as column 3. What test to use?
first column: number of interventios (surgery) that patients went through: values are 1, 2, 3, 4
second column: number of patients that went through those interventions: values are 27, 9, 3, 1
third column: how many died after they underwent respectively 1, 2, 3, or 4 interventions: values are 9, 4, 2, 0. So the one guy that went through 4 interventions did not die, 27 went through 1 intervention and out of these 9 died, etc.
All I want is to find what corelation is between the number of interventions and the mortality. I hope I was clear.
I have that analysis installed, and I have no ideea how to recess something …
