Dear Friends,
I have started to write some codes for RSTAN, I have a general question
regarding likelihood function.
Below you can see a simple structure of RSTAN model. For most of the codes, in
the "model" block, I saw priors (hyperpriors) and likelihood functions.
In a few programs, I don't see a likelihood function (such as the model shown
below). Has any default function been defined in RSTAN or I am mistaking?
I would appreciate your help.
Regards,
Peri
model.stan <- "data { int<lower=0> i;
.
.
.
}
parameters {
real Mi;
real<lower=0> De;
real R[i];
}
model {
for(i in 1:I) {
b[i] ~ normal(R[i], C[i]);
R[i] ~ normal(Mi, De);
}
Mi ~ normal(0, 10);
De ~ uniform(0,sigma);
}"
stan(model_code = model.stan,
data = data,
init = rep(.),
chains = .,
iter =iter1,

refresh = 50000
