Hello,

I have a question about for loop. Since I have different area s and for each area, it has different amount of residents n_s. So I record the starting number and ending number of each area into two separate vector. And call them in the for loop.

The for loop structure like:

```
for (k in 1:s) {
for (j in 1:n_s){
int index = k*n_s-n_s+j;
# compute the posterior
```

So mine is:

```
for (k in 1:s) {
int start_point = starting[k];
int end_point = ending[k];
for (j in start_point:end_point){
int index = j;
# compute the posterior
```

And for starting and ending:

```
data {
int s;
int N;
vector[s] starting;
vector[s] ending;
}
```

I receive the error message as:

```
SYNTAX ERROR, MESSAGE(S) FROM PARSER:
variable definition base type mismatch, variable declared as base type: int variable definition has base: real error in 'model33908d47a8_tweedie' at line 62, column 37
-------------------------------------------------
60: // likilihood of tweedie distribution
61: for (k in 1:s) {
62: int start_point = starting[k];
^
63: int end_point = ending[k];
-------------------------------------------------
Error in stanc(file = file, model_code = model_code, model_name = model_name, :
failed to parse Stan model 'tweedie' due to the above error.
In addition: Warning message:

```

What should I do to solve this problem? Thank you very much for your help in advance.

With appreciation,
