Ok so I have an optimization problem that boils down to finding the primary axis of a set of 16 points in 3D space
The code I have that I sorta mindlessly copied from someone else has two methods of doing this. the one that claims to be less accurate does a least-squares fit. the one that claims to be more accurate calculates the covariance matrix and a power iteration
What is actually different between these too methods in terms of the result? in addition, if I wanted to prioritize one of the dimensions of the points (theyre colors and perceptually I want to weight towards green), how would I go about doing that?

Hi @christianp --
Thanks for your timely response,
and of course, foremost + especially, thanks for supporting $\LaTeX$ at all,
and thanks for having raised the max. numbers of characters (1729) to a level which enables scientific correspondence.Could you please suggest where/how to learn (and possibly ask) more systematically about ... (focussing on my single-most-pressing remaining frustration) ... which mastodon "instance(s)" might already support all that AND "basic formatting" ??
