Standard error and confidence interval
Description
These wrapper functions compute the standard error (SE) or the confidence
interval (CI) of the values in x
. If na.rm
is TRUE
,
missing values are removed before the computation proceeds.
Usage
se(x, na.rm = FALSE)
CI(x, level = 0.95, na.rm = FALSE)
Arguments
x |
a numeric vector or an R object which is coercible to one by
|
na.rm |
logical. Should missing values be removed? |
level |
the confidence level required. |
