are.parln3.valid {lmomco} | R Documentation |
The distribution parameter object returned by functions of this package such as by
pargum
are consistent with the corresponding distribution,
otherwise a list would not have been returned. However, other
functions (cdfln3
, qualn3
, and
lmomln3
require consistent parameters to return the cumulative
probability (nonexceedance), quantile, and L-moments of the distribution,
respectively. These functions internally use the are.parln3.valid
function.
are.parln3.valid(para,nowarn=FALSE)
para |
A distribution parameter list returned by parln3 . |
nowarn |
A logical switch on warning surpression. If TRUE then options(warn=-1) is made and restored on return. This switch is to permit calls in which warnings are not desired as the user knows how to handle the returned value—say in an optimization algorithm. |
TRUE |
If the parameters are ln3 consistent. |
FALSE |
If the parameters are not ln3 consistent. |
This function calls is.ln3
to verify consistency between
the distribution parameter object and the intent of the user.
