| skewhypCheckPars {SkewHyperbolic} | R Documentation |
Given a set of parameters for the skew hyperbolic Student t-distribution, the function checks that the parameters are in the correct range, and that the set has the correct length of 4.
skewhypCheckPars(param)
param |
A numeric vector of proposed parameters for the skew hyperbolic t-distribution. |
The vector param should be of the form
c(mu,delta,beta,nu).
If either delta or nu is not greater than zero an error
message is returned.
If the vector param does not have a length of 4 then an error
message is returned.
A list with components:
case |
Either 'error' or 'normal', as identified by
the function. |
errMessage |
An appropriate error message if an error was found, otherwise an empty string. |
