Hi, Problem statement: There are two variables Y, X. Y is a response from X. I want to find a closed form formula to express Y in terms of X. Comments: I tried with simple polynomial basis but its not a good fit due to the non-linear nature of Y. Are there any set of functions or algorithm to estimate this closed form transformation? It could involve any trug, algebraic functions etc... Thank You, Nagu

Without having a model, it seems to be unsensible to look for such a function, since there may be an infinte number of functions fullfilling your criterion. Uwe Ligges
