Dear Bugs Users, I am running a spatial random effects model in WinBUGS 1.4.1 with GeoBUGS (code below). The model compiled, I loaded most of the inits and generated the remaining ones, which all worked as usual. However, when I started to update, I got a Rejection1 error in the bottom left-hand corner of the screen. I did some poking around in the manual and on the list, but there were no answers there. If I continue to hit the update buttom, WinBUGS will continue to update, but each iteration I continue to get this message. Can anyone tell me what this means? Thanks in advance, Dave. model{ for(i in 1:152){ for(j in 1:24){ ycs[j,i] ~ dpois(p.ycs[j,i]) log(p.ycs[j,i]) <- exp.kill[j,i] + alpha[1,j] + S[j,i] ed[j,i] ~ dpois(p.ed[j,i]) log(p.ed[j,i]) <- exp.kill[j,i] + alpha[2,j] + S[j,i] ar[j,i] ~ dpois(p.ar[j,i]) log(p.ar[j,i]) <- exp.kill[j,i] + alpha[3,j] + S[j,i] hrw[j,i] ~ dpois(p.hrw[j,i]) log(p.hrw[j,i]) <- exp.kill[j,i] + alpha[4,j] + S[j,i] mean[j,i] <- (1/4)*(p.ycs[j,i] + p.ed[j,i] + p.hrw[j,i] + p.ar [j,i]) } } for(k in 1:152){ mu[k] <- 0 } for(j in 1:24){ S[j,1:152] ~ spatial.exp(mu[], x[], y[], tau, phi, 1) alpha[1,j] ~ dnorm(0, 0.001) alpha[2,j] ~ dnorm(0, 0.001) alpha[3,j] ~ dnorm(0, 0.001) alpha[4,j] ~ dnorm(0, 0.001) } tau ~ dgamma(0.01, 0.01) phi ~ dunif(0.33, 6) } -- Dave Armstrong University of Oxford Department of Politics and International Relations Center for Research Methods in the Social Sciences Nuffield College e-mail: [log in to unmask] web: www.davearmstrong-ps.com Facts are meaningless.
