Description Objects from the Class Slots Extends Methods Author(s) References See Also
A class for the results of an XSA analysis.
Objects can be created by calls of the form new("FLXSA", ...)
and are output by
calls to FLXSA
.
survivors

. Numbers-at-age in the final
age of a cohort
se.int
:Object of class "FLQuant"

numbers-at-age in the final year

:Object of class "FLQuant"
. External standard errors of
numbers-at-age in the final year
