Constrained Curve Fitting in KDB

[megan_mcp]

Hi ,

This looks similar to Polynomial fitting – lsq least-squares matrix equation solution |Reference | kdb+ and q documentation – Kdb+ and q documentation (kx.com)

Or another option is to use embedPy (or the PyKX version PyKX under Q) to import a Python library and use it directly. Running PyKX under q – PyKX

Let me know if this helps!

Thank you  ! the lsq won’t fit our use case since we want the coefficients to be strictly greater than zero.

We’ll have a look at embedPy – was just hoping somebody had possibly written a native kdb implementation already.
