Hello. I need some advice from you guys. I have a table of 92 rows with 4 values for variables x,y,z,t in each row. These are all experimentally measured out values for function t = f(x,y,z) My goal is to get the equations, most likely with some form of interpolation. Is there any software I...

Jack, thank you for this interesting answer. I thought about it for a while. But does not your step 3 assume I can have numeric value of z, in order to substitute it in functions obtained from interpolation, and get A(z), B(z), C(z), D(z), E(z) ? I can get z to be the same for some set of tests...

This is what the scientific work deals with: t is success rate for a type of specific very precise machines that is easy to calculate x is skillfulness of worker, which is also able to be determined in terms of tests he does and certificates he already has. y is readiness of machine, which is...

I am not sure what you are asking exactly. What I have is a big set of point where for some x and y predetermined and set value t has been experimentally measured. And I want to show it depends from z too and to get the equation.

Yes, that was part of my question, if this problem is formulated ok at all. It is just that some effort realized depends on two components that are measurable and one that is certainly not. So I was wondering is it possible to get math equation between the four, if we have multiple points where...

Hello. A whole decade passed since I graduated mathematics and shifted to other profession, so my knowledge is very rusty. There is an important problem for a scientific work that I need help for. Let's say factor t is being calculated from factors x, y and z, all some parameters from living...
