Description Usage Arguments Value See Also Examples
This function compares all possible pairwise comparisons, as supplied by
formula
, in terms of the transformed proportion above the cut. This
is an effectsize like measure of the differences between two groups as the
cut point(s) in the distribution. See

data 
The data frame used for estimation  ideally structured in a tidy format. 
formula 
A formula of the type 
cuts 
Optional vector of cut scores. If supplied, the ECDF will be guaranteed to include these points. Otherwise, there could be gaps in the ECDF at those particular points (used in plotting the cut scores). 
ref_group 
Optional. A character vector or forumla listing the
reference group levels for each variable on the right hand side of the
formula, supplied in the same order as the formula. Note that if using the
formula version, levels that are numbers, or include hyphens, spaces, etc.,
should be wrapped in back ticks (e.g.,

Tidy data frame of the proportion above the cutoff for each (or selected) groups.
