Dimension mismatch in subset expression in R/JAGS
I am new to using rJags. I have a jags model in R (version 4.3.0 (2023-04-21 ucrt)) using rjags (rjags_4-14).
I am trying to add a random intercept of "creek" (Clean in the data below) to my model. When using the code below, I get the error:

Rjags error: node inconsistent with parents works with one dataset but not the other
I have a jags model in R (version 4.3.0 (2023-04-21 ucrt)) using rjags (rjags_4-14).
The model runs without error for one dataset (named below: "works"). With a different dataset, which is the "works" dataset with additional observations (named…

Calculating I2 from a Bayesian Model Network metanalysis
I am conducting a network metanalysis using both Bayesian (using JAGS run throug R with the package R2JAGS) and frequentist model and, as a form of heterogeneity, I would like to calculate I2.
However, after computation, I have complete different…

Power prior in R2jags
In a fixed power prior model, the model is set up as:
Suppose that the event follows a Bernoulli distribution with probability p_i, what I want is to raise the Bernoulli likelihood to the power of w in jags:
mod1<-function(){
for(i in 1 : N) {

Hidden state output from jags model in R
Does the "jags" function of R2jags give estimated states output when estimating a state space model?
Or is it to be derived manually using estimated mean/medians of parameter values.

Latent variable estimation with binary and continuous indicators in JAGS
I am using R2jags to estimate latent factor using both binary and continuous variables. I was wondering wether jags command from R2jags can handle both binary and continuous variables at the same time. I tried to find articles explain the types of…

effectiveSize() output different from jags()
I am fairly new to JAGS and I am using the jags() function from the package R2jags to run some occupancy models. However, the output from jags() in terms of effective sample size is different from what I get from using effectiveSize() from the coda…

Error loading archived version of R2jags (0.6.1) with JAGS 4.3.0 installed
I need to test a model in an old version of JAGS and R2jags. I have JAGS 4.3.0 installed on my computer and get an error when trying to load in R2jags 0.6.1. I am able to load R2jags 0.6.1 just fine when I have JAGS 4.3.1 installed. Perhaps the…

Index out of range taking subset error with JAGS while performing network metanalysis
I was trying to develop a model to run a network metanalysis with jags and tried to use a previous code I've already used with WinBUGS (and worked properly).
However, when I try to use it with JAGS it gives me a coding error, but it still works…

How to make leave-one-out cross-validation using R2jags or rjags
I'm trying to make leave-one-out cross-validation using R2jags.
I do it easily when I use R2WinBUGS instead with the same codes, but jags() give me this error :
