A list with one element for each parameter in which
is also returned invisibly.
Each element is a vector of length two or a matrix with two
columns, giving the lower and upper limits of each confidence
interval.
The profile confidence intervals may not have confidence coefficient
ci
, because the usual asymptotic properties of maximum
likelihood estimators may not hold.
For the GEV model, the usual asymptotic properties hold when the
shape parameter is greater than 0.5 (Smith, 1985).
