I have given function values say "$y$" which is dependent on $x$ and $\log(100-x)$, how shall I solve this problem using linear regression - as in I want my model to be like $$y = Ax + B\log(100-x).$$
I could do it by taking $x$ as one variable and $100-x$ as another, but is that wrong?
Is there any other way this could be done using multiple linear regression where $x$ and $\log(100-x)$ are taken as different variables?
Am I committing a mistake by taking $x$ and $\log(100-x)$ as different variables since they are dependent on each other?
