I'm working on a linear regression formula for a forecasting model. My model requires non-negative predictions.
The model works well when predictors have big values; however, I get negative predictions pretty often when predictors have small values.
I was hoping to find a solution whereby the model wouldn't be linear but somewhat exponential to converge to 0, but not getting there unless the variables are both 0.
This is an example of my constant and coefficients for two variables:
