Hi Peter:
What is the problem for which this is going to be the solution?
Statistical analysis goes in the other direction, as you acknowledge. I can give you a formula which will discribe a plot of normal/standard normal data but there are a very large number of points that will lie on one of these curves. Hence the question: what are you wanting to do?
