It's a bit of a light hearted approach. youtube.com/watch?v=Qm84XIoTy0s Nov27 awarded Notable Question Oct3 awarded Popular Question Aug19 awarded Notable Question May25 comment Submit papers: arxiv or vixra? I hate you people. I just spent an hour reading astrophysics papers on viXra. Who the hell is Jeffrey Joseph Wolynski? Woah!

I have finally worked through your solution and arrived as a $\pm$ value. See my updated question as I still have some queries I am uncertain of. Apr24 revised Finding uncertainty in the slope/intercept for a non-linear least squares fit Provided better data for the table, clarified some of the algebra letters, and provided an update. Apr19 comment Finding uncertainty in the slope/intercept for a non-linear least squares fit Thanks for that. Just wanted to check that in your last equation you intended $\hat\sigma$ and not $\hat\sigma^2$. So $\hat\sigma$ is $\sqrt{\hat\sigma^2}$ Apr18 comment Finding uncertainty in the slope/intercept for a non-linear least squares fit Thanks for that. I'm not familiar with the notation, but it's making some sense. Wondering though, what is $\hat\sigma$ Apr18 asked Finding uncertainty in the slope/intercept for a non-linear least squares fit Apr8 comment Finding points along a plot in Matlab @macydanim: One more small question. What would I need in order to match a polynomial to it instead of finding a straight-line match? Apr8 comment Finding points along a plot in Matlab @macydanim Thanks once again. I've adapted it for my specific needs and it seems to work quite well. Thanks.
