confint2 is a generic function for creating confidence intervals from
various statistical information (e.g., confint2.default) or
object classes (e.g., confint2.boot). It is an alternative to
the original confint generic function in the stats
package.
confint2(obj, ...)depends on the particular method of confint2, but usually a data.frame
with a column for the parameter estimate ("est"), standard error ("se"),
lower bound of the confidence interval ("lwr"), and upper bound of the confidence interval ("upr").
object of a particular class (e.g., "boot") or the first argument
in the default method (e.g., the obj argument in confint2.default)
additional arguments specific to the particular method of confint2.
confint2.default for the default method,
confint2.boot for the boot method,
