initial points for arms in package HI
Dear R-users
I have a problem choosing initial points for the function arms()
in the package HI
I intend to implement a Gibbs sampler and one of my conditional
distributions is nonstandard and not logconcave.
Therefore I'd like to use arms.
But there seem to be a strong influence of the initial point
y.start. To show the effect I constructed a demonstration
example. It is reproducible without further information.
Please note that my target density is not logconcave.
Thanks for all comments or...
