For loop issus caused by unbalanced group number

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:
In readLines(file, warn = TRUE) :
  incomplete final line found on 

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

With appreciation,

Both starting and ending should be declared as integer arrays in the data block, as in

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

But trying to do a Tweedie likelihood with an unknown shape parameter is going to be painful.

Thank you very much for your help, Ben. The reason why I made this mistake is because I didn’t distinguish the vector of real and the vector of integers.

That is my research topic. So I can’t find any other way out. I have to work on it…= = So far not that bad.
