Question about compute_prevalence #14

Closed zkamvar closed 5 years ago

zkamvar commented 5 years ago

Okay,

So, I'm going through the anthro_prevalence function once again to try and figure out what the h*ck is going on and I stumble across

https://github.com/dirkschumacher/anthro/blob/97dcb8b435a4961d44c4fdc2cc89dc810bf2fea5/R/prevalence.R#L478-L479

and I'm just thinking, what madness is this? I'm already super tired because I've already clawed my way up to this point from the compute_prevalence_zscore_summary() function and now I realize I have to travel up yet another two calls to figure out where cutoff_dir and cutoffs came from.

After some (soul) searching, I realize that this function evaluates to zscore_prev > y or zscore_prev < y. Am I correct?

Yes. It does a simple comparison in the end.
