Linear least squares with selective parameter fitting
sorry I wrote it wrong - I have fixed the equation so that the model is linear in $a,b$

Integration problem
Thank you both for your comments. I have edited the question above to give a specific example. Quad precision does seem to give an acceptable result, but double precision is disappointing.

Method to compute $a^n - b^n$
@lightxbulb so you mean to use a Gauss-Legendre quadrature or similar? Rather than directly evaluating the analytic solution?

Method to compute $a^n - b^n$
If it helps we can assume $a,b$ are in $[1,2]$. The computation comes from computing an integral $\int_b^a x^{n-1} dx$
