Hernes model of proportion of a cohort ever-married by age
----------------------------------------------------------

        ^hernes^ var_age var_rate [^if^ exp] [^in^ range] [^,^ ^method(^string^)^]


Description
-----------

^hernes^ estimates the Hernes model and yields five parameters: a, b, k, A and
F0. In addition, it generates the estimated age-specific cumulative marriage
rates.


Options
-------

^method(^string^)^ specifies the method for estimating the Hernes model:
    ^hernes^ for Hernes method and ^nl^ for nonlinear least squares method.
    The default method is the nonlinear least squares method.


Examples
--------

   . ^hernes age rate,method("hernes")^
   . ^hernes age rate,method("nl")^
   . ^hernes age rate if age<=24^
