1 | RVA(pre, post, rvacat)
|
pre |
The pre-impact IHA statistics, i.e. the output of
|
post |
The post-impact IHA statistics. |
rvacat |
The RVA categories, as defined by e.g. RVA_categories(pre) |
The boundaries
argument defines cutoffs relative to the mean
(if parametric = TRUE
) or median (if parametric = FALSE
),
e.g. boundaries = c(-17, 17)
represents cutoffs at the 33rd and
67th percentile when parametric = FALSE
, and
boundaries = c(-0.5, 0.5)
represents cutoffs at +/- 0.5 standard
deviations from the mean when parametric = TRUE
.
