Non-point null hypothesis testing with lmBF() #109

Closed cvonbastian closed 6 years ago

cvonbastian commented 6 years ago

Hi Richard,

I'm currently running a couple of linear models with lmBF() and was wondering whether there's an equivalent to setting nullInterval=c(-Inf,0) in ttestBF(). I was thinking to do something along the lines of comparing an H1 model in which the prior for a particular factor is set to a positive half-Cauchy to an H0 model where the prior for the same factor is set to a negative interval, but couldn't figure out a way to set custom priors for the lmBF().

Any pointers would be greatly appreciated!

Many thanks and best, Claudia

Hi Claudia,

You can do this: http://bayesfactor.blogspot.co.uk/2015/01/multiple-comparisons-with-bayesfactor-2.html

I believe Candice Morey has used this in a paper; you might want to ask her for details on how she reported it.

Best, Richard

Thanks so much, Richard, that's exactly the kind of thing that I was looking for! I'll get in touch with Candice regarding her paper, too!

Best, Claudia
