This code implements the 1D polynomial regression method. This makes it a nice, straightforward way to model curves without having to model complicated non-linear models. Values of τ 0, d were calculated by linear regression of shear rate versus steady shear stress data using a third order polynomial and the subsequent extrapolation of shear stress to shear rate equal to zero. It is a great tool. You should remove one of the corresponding variables. And yes you would have to rename them in that case I'm the new software. Accelerating the pace of engineering and science.

Updated Long story short, don't use a fit with a CVRSquare "too different" (magnitude left to your imagination) than the regular RSquare. But setting $\mathbf{a}=(\mathbf{K^\top K})^{-1} \mathbf{K^\top Y}$ does not work, I think the reason why is since the K and T elements of the matrix $\mathbf{K}$ are linearly dependent.

If x 0 is not included, then 0 has no interpretation. Teachers can find useful math resources for the classroom. Excellent code, I have been looking for multivariate polynomial regression tools for quite some time. The fits are limited to standard polynomial bases with minor modification options. Otherwise, I have to run it those optimizers which might not be this good. Hence, you don't need both $K$ and $T$ - you should get rid of one of them.
