SBC: I cannot understand the parameter log_lik in an example code

Modeling
3

Thank you for telling me, but I cannot understand, :’-D
I implement sbc for my model described in the page in which made a rank statistic for a single model parameter w. But my model contains the following multi parameter.

parameters{
real w;
real <lower =0>dz[C-1];
real m;
real <lower=0>v;
}

Then, how to add the other parameters in the above code for rank statistics?

Now my code of rand statistic is
int ranks_[1] = {w > w_};

I think it should be change like following? but it did not work.
int ranks_[2];

ranks_[1] = {w > w_};
 ranks_[2] = {m > m_};
