Uses Newton-Raphson to estimate the parameters of the Gumbel distribution.
mlgumbel(x, na.rm = FALSE, ...)mlgumbel returns an object of class
univariateML.
This is a named numeric vector with maximum likelihood estimates for mu
and s and the following attributes:
modelThe name of the model.
densityThe density associated with the estimates.
logLikThe loglikelihood at the maximum.
supportThe support of the density.
nThe number of observations.
callThe call as captured my match.call
shape and sigma.
a (non-empty) numeric vector of data values.
logical. Should missing values be removed?
sigma0 is an optional starting value defaulting to 1.
rel.tol is the relative accuracy requested, defaults to
.Machine$double.eps^0.25. iterlim is a positive integer
specifying the maximum number of iterations to be performed before the
program is terminated (defaults to 100).
