Non-linear regression

Question

1. Can we use Linear Regression tool for non-linear problem? There are forms of non-linear equations that cannot be approximated by Logistic or any other regression tools - for example, I may have an exponential growth problem or multinomial (say, quadratic) forms. How do you tackle such types of regressions, if you do not want to transform the non-linear into linear form?

2. Can you help find some resources which discuss about the Alteryx Prescriptive Analytics?

Thanks,

Hi @urezwan

1. If the target variable cannot be transformed to a linear form, the Linear Regression tool might not be appropriate for the analysis. Alteryx can utilize R packages that would be more appropriate, but the specific package used will depend on the use case. If you're looking for an Alteryx Predictive tool for non-linear, continuous target regression problems, I suggest looking into the Spline Model tool.

2. Here's the official documentation:
