A character string "name" naming a distribution for which the
corresponding density function (dname), the corresponding
distribution function (pname) and the quantile function
(qname) must be defined (see for example
GammaDist)
...
arguments passed to other functions, currently not used.
Value
named list, names correspond to distribution parameters. In case of
failure, the same list with NA values is returned.
Details
lmom.start uses L-moments for parameter estimation. In most
cases it relies on functionality of the lmomco
package. Currently available distributions are: "gamma",
"genlog", "gev",
"gumbel", "logis",
"lnorm", "norm",
"pe3", "weibull".
mom.start uses moments (e.g. mean, standard deviation) for
parameter estimation. Some estimates are precise, others only
approximations that provide reasonable starting values. Currently
available distributions are: "gamma",
"gumbel", "logis",
"lnorm", "norm", "weibull".
dist.start calls first lmom.start to estimate
parameters. In case of failure mom.start is called, hopefully
producing reasonable parameter estimates.
