问题
I would like to ask here one question about (I assume) the regression model. My task is to deduce the equation from the 4-dimensional dataset. During my research, I have not noticed any regression model that would fit my needs, primarily due to the fact that the equation that I am trying to approximate is not linear, whereas the regression models are mainly linear.
Is there any suggestion for the regression method which cold help me to solve my task?
