Can someone solve this so I can get a direct equation for Cohen's d? #statspic.twitter.com/IlJzWVOGLc

with rl1 and rl2 being the reliabilities. but if I was doing that in my code, I'd prefer multiple lines, way more readable
Yes, just wondering if there was a neat equation for presentation purposes. @dingding_pengpic.twitter.com/UOX0ghZlfQ

aaaah, okay! Now I see. I actually think that the multiple line solution is neater, don't think you can simplify much
-
Oh well. I'm not particularly good with algebra, so I'm not the right person ti ask to rearrange stuff without errors! :)
@dingding_peng -
If you're good, maybe you can solve this one! :) http://emilkirkegaard.dk/en/?p=6570 It's something with infinite series that converge
@dingding_peng -
I tend to solve everything using WolframAlpha, not sure whether that qualifies as a skill...

Don't think WA works for this one. Basically have to show (5) from (1-4). Empirically, it works out (when n = large).
