I am doing a simple regression model with WinBUGS via R2WinBUGS. Results appear ok, however WinBUGS keeps showing this line and I don't know why:
command #Bugs:gen.inits cannot be executed (is greyed out)
Does someone have an idea? Thanks!
The R code calling WinBUGS:
# Prepare data
ni = 12 #Nb of tagging year
prL <- c(0.13,0.23,0.28,0.22,0.29,0.25,0.31,0.32,0.32,0.40,0.33,0.35) #Proportion of tag lost
input.tlr <- list(ni=ni,prL=prL)
# Generates intial values for two chains
nbchains = 2
init1 <- list(beta1=runif(1,-1,1),beta2=runif(1,-1,1),tauG=rgamma(1,1,1))
init2 <- list(beta1=runif(1,-1,1),beta2=runif(1,-1,1),tauG=rgamma(1,1,1))
inits <- list(init1,init2)
# Call WinBUGS
parameters <- c("gamma","beta1","beta2","tauG")
out.tlr <- bugs(data=input.tlr, inits=inits, parameters=parameters, "tlr.txt", n.chains=2, n.iter=20000, n.burnin=5000,n.thin=1,debug=TRUE)
The WinBUGS code is:
model {
###### Tag lost rate model ######
for (i in 1:ni) {
prL[i] ~ dnorm(gamma[i],tauG)
gamma[i] <- beta1 * log(i-0.5) + beta2
}
### Priors
beta1 ~ dnorm(0,0.001)
beta2 ~ dnorm(0,0.001)
tauG ~ dgamma(0.001,0.001)
} # End model
And the WinBUGS output is:
display(log)
check(C:/Users/AppData/Local/Temp/RtmpG8dxh1/tlr.txt)
model is syntactically correct
data(C:/Users/alebris/AppData/Local/Temp/RtmpG8dxh1/data.txt)
data loaded
compile(2)
model compiled
inits(1,C:/Users/AppData/Local/Temp/RtmpG8dxh1/inits1.txt)
chain initialized but other chain(s) contain uninitialized variables
inits(2,C:/Users/AppData/Local/Temp/RtmpG8dxh1/inits2.txt)
model is initialized

command #Bugs:gen.inits cannot be executed (is greyed out)
