I am having 6-7 input variables and 1 output variable. I want to make a model to express that 1 output variable in terms of all the 6-7 input variable. It is a non-linear type relation. I need a software/tool to predict the model.
It is easy to find a software for nonlinear regression. In fact, eviews, minitab, SPSS, SAS, MATLAB, R , etc. can be used for non-linear regression of the output variable on the 6-7 input variables.
