hello team, i am running my model and data below, the model enters and data is loaded but when it comes to compile, i get an error message "made use of undefined node DO" WHAT COULD BE THE PROBLEM AND WHAT IS THE SOLUTION.
MODEL
model
{
for (i in 1:site) {
for (j in 1:farm) {
y[i , j] ~ dbern(p[i , j]) ;
logit(p[i, j])
I guess a potential issue might be the fact that DO contains NA and this line here may cause WinBUGS to choke:
logit(p[i, j])
@raymond yes it goes past it but my worry is that how can i present data that wasn't collected because 0 is a value in DO .dissolved oxygen
One approach would be to convert from 2-d arrays of nodes to 1-d arrays of nodes drop the values which weren't connected.
So instead of
for (i in 1:site) {
for (j in 1:farm) {
logit(p[i, j])
