parln3 {lmomco} | R Documentation |
This function estimates the parameters of the Log-Normal3 distribution given
the L-moments of the data in an L-moment object such as that returned by
lmom.ub
. The relation between distribution parameters and L-moments
is seen under lmomln3
.
parln3(lmom, zeta=NULL, checklmom=TRUE)
lmom |
A L-moment object created by lmom.ub
or pwm2lmom . |
zeta |
Lower bounds. |
checklmom |
Should the lmom be checked for validity using the are.lmom.valid function. Normally this should be left as the default and it is very unlikely that the L-moments will not be viable (particularly in the tau_4 and tau_3 inequality). However, for some circumstances or large simulation exercises then one might want to bypass this check. |
An R list
is returned.
type |
The type of distribution: ln3 . |
para |
The parameters of the distribution. |
source |
The source of the parameters: “parln3”. |
