Apologies for the transgression, which is; ironically; a direct result of my personal progress in JSL.
A very helpful computer scientist in my organization is trying to translate something initially written in JSL to Python. Specifically, the challenge is how to reproduce what the JSL function 'Vec Quadratic()' is doing? See also the attached example table .
Background:
The JSL application to be translated creates formula columns for the confidence and prediction intervals. The formulas are then used to calculate the values of the confidence and prediction intervals for some user specified value of x, aka independent variable.
Questions:
Screenshots for orientation:
- What we want to achieve in Python (results inside the red frame)

- How the columns shown above were generated
