TypeError: func is not a function

[alariej]

Hi, I am getting "TypeError: func is not a function" at:

levenberg-marquardt/src/errorCalculation.js

Line 20 in 155bf0c

error += Math.pow(data.y[i] - func(data.x[i]), 2) / weightSquare[i];

when building my Node application.

I'm running a Ubuntu 22.04 server with Node 18.

I have both "ml-levenberg-marquardt": "^4.1.3" and "@types/ml-levenberg-marquardt": "^3.1.3" installed via NPM.

Any idea what I'm doing wrong?
