Hello,

I a looking for a way to create a curve based on multiple independent variables. The result should be a function of those variable, f(x,y,...,z). For example, if I have the above dataset, is there a function similar to linest that can generate the best fit curve to produce something like:

f(x,y) = a * x^b + c * y^d

or

f(x,y) = a * x^b * y^c

?

I'm currently interested in generating power series functions, so I have a used those as output examples. But I'm interested in being able to create all types of multiple variable functions from a given dataset.

I've used linest in the past for single independent variable functions, but I can't seem to find anything to work with multiple variables.

Thanks!
