This function calculates an Index of Person Separation, that is the proportion of person variance that is not due to error.
Usage
pairwise.SepRel(pers_obj, na.rm = TRUE)
Value
An object of class c("pairwiseSepRel","list").
Arguments
pers_obj
an object of class "pers" as a result from function pers.
na.rm
a logical evaluating to TRUE or FALSE indicating whether NA values should be stripped before the computation proceeds.
Details
none
