distrib |
character string indicating the probability distribution to fit |
lmom, ... |
L-moments and further parameters for |
probability_distribution_attrname |
attribute name for probability distribution |
x |
vector containg sample. It is utiled to calculete L-moments in case |
nmom, sort.data, ratios, trim |
arguments for |
indices |
optional index or tag character vector of the same length of |
spi.scale |
integer value or |
correction |
numeric value correction for the 3rd (and higher) L-moment estimation. Default is |
pel_x
and pel_lmom
are wrapper functions of pel
whose first argument is x
or lmom
respectively.
A numeric vector containing the parameters of the selected probability distribution. It is a list in case of selection of several probability distributions (i.e. length(distrib)>1
).
