rvci {rv} | R Documentation |
Computes credible (uncertainty) intervals for a given vector, given quantiles or the size of the middle interval
rvci(obj, interval=0.95, one.sided=FALSE, left=TRUE)
obj |
random scalar or vector |
interval |
size of the middle interval or the quantile range of the interval |
one.sided |
logical, FALSE if two-sided interval is desired |
left |
logical, indicating if the left one-sided interval is desired |
If interval
is of length two or more, the return
value will be the quantiles given by range(interval)
.
For two-sided intervals,
an array of numbers of dimension c(2,length(x))
,
for one-sided intervals,
a vector of the same length as x
