are.par.valid {lmomco} | R Documentation |
This function is a dispatcher on top of the are.parCCC.valid
functions,
where CCC
represents the distribution type: exp
, gam
, gev
, glo
, gno
,
gpa
, gum
, kap
, nor
, pe3
, ray
, revgum
, wak
, or wei
. Internally, this function is called
only by vec2par
in the process of converting a vector into a proper
distribution parameter object for this package.
are.par.valid(para,...)
para |
A distribution parameter object having at least attributes type and para . |
... |
Additional arguments for the are.parCCC.valid call that is made internally. |
TRUE |
If the parameters are consistent with the distribution specified by the type attribute of the parameter object. |
FALSE |
If the parameters are not consistent with the distribution specified by the type attribute of the parameter object. |
