Are the Distribution Parameters Consistent with the Slash Distribution
Description
Is the distribution parameter object consistent with the corresponding distribution? The distribution functions (cdfsla
, pdfsla
, quasla
, and lmomsla
) require consistent parameters to return the cumulative probability (nonexceedance), density, quantile, and L-moments of the distribution, respectively. These functions internally use the are.parsla.valid
function.
Usage
are.parsla.valid(para, nowarn=FALSE)
Arguments
para |
A distribution parameter list returned by |
nowarn |
A logical switch on warning suppression. If |
Value
TRUE |
If the parameters are |
FALSE |
If the parameters are not |
Note
This function calls is.sla
to verify consistency between
the distribution parameter object and the intent of the user.
