Closes #336

Note that there appears to be errors in the formulas JASP is using. @mattansb Can you run some simulations like I describe in #336 and see if we need to modify the formulas to divide the SEs by (1 - r_rbs^2) ?

Also, it would be nice typeset equations and math symbols in the HTML help using Mathjax for pretty equations, rather than simply omitting the symbols as is currently done. It just takes adding mathjaxr to Suggests (no downstream dependencies). Does that sound good to you @mattansb @strengejacke ?

Does that sound good to you @mattansb @strengejacke ?

Yes, sounds good!

[mattansb]

@bwiernik I'll run these sims and get back to you.

Some checks seem to be failing related to mathjaxr...

[bwiernik]

@strengejacke On some further testing, it looks like mathjaxr would need to be in Imports, not Suggests. Are you still okay with adding it? I think it's worth it to make the equations more readable in the place where most users will see them.

[mattansb]

I say no - I think having \eqn{pretty}{ugly} is as good as we're gonna get here for now :/

Thanks for your work on this and your very detailed comments :)
