rvci | 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
.
