coef
extracts the parameters from a fitted model object.
# S4 method for hansentree
coef(object, ...)# S4 method for browntree
coef(object, ...)
coef
applied to a hansentree
object returns a named list containing the estimated \(\alpha\) and \(\sigma^2\) matrices(given as the alpha.matrix
and sigma.sq.matrix
elements, respectively) but also the MLE returned by the optimizer
(as sqrt.alpha
and sigma
, respectively).
The latter elements should not be interpreted, but can be used to restart the algorithm, etc.
coef
applied to a browntree
object extracts a list with three elements:
sigma
the coefficients of the sigma matrix.
theta
a list of the estimated optima, one per character.
sigma.sq.matrix
the sigma-squared matrix itself.
fitted model object.
additional arguments, ignored.
