Hi all, I am constructing a likelihood involving the following lbeta(j + a, k - j + b) where j,k are constants and a and b are parameters (>0). While doing the optimization, the error sometimes occurs, In lbeta(j + a, k - j + b) : underflow occurred in 'lgammacor' Is there a way to avoid it? I am not sure what's being used in ' 'lgammacor''. Thanks! ----- ################################################### PhD candidate in Statistics School of Mathematics, Statistics and Actuarial Science, University of Kent ################################################### -- View this message in context: http://r.789695.n4.nabble.com/how-to-avoid-this-underflow-occurred-in-lgammacor-tp4532940p4532940.html Sent from the R help mailing list archive at Nabble.com.
