Hi everyone,

I am trying to fit a weighted logistic regression model (using weights as the survey weights).

My code is as follows. Here w corresponds to the weights:

```
data {
int<lower=1> N;
int<lower=1> K1;
int<lower=0,upper=1> y1[N];
matrix[N,K1] x1;
real w[N];
}
parameters {
real alpha1;
vector[K1] beta1;
}
model {
beta1 ~ normal(0, 5);
alpha1 ~ normal(0, 5);
for (k in 1:N)
target+= w[k]*bernoulli_logit_glm_lpmf(y1[k]|x1,alpha1,beta1);
}
```

However, I am getting the following error:

SYNTAX ERROR, MESSAGE(S) FROM PARSER:

No matches for:bernoulli_logit_glm_lpmf(int, matrix, real, vector)

Available argument signatures for bernoulli_logit_glm_lpmf:

bernoulli_logit_glm_lpmf(int[ ], matrix, real, vector)

bernoulli_logit_glm_lpmf(int[ ], matrix, vector, vector)

It seems there is a problem of how I define parameters inside the `bernoulli_logit_glm_lpmf`

and I couldn’t figure it out by myself.

Can somebody help me to figure this out?

Thank you.
