I having been running in circles with this same issues for hours today, to no avail. Forums have not led me anywhere in terms of getting closer to resolving (what should be) a very simple issue (see stan below). I am getting the “;” expected after variable declaration (referenced to y[N]; on line 4)…

I encountered the same problem yesterday. For your int<lower=1, upper=K> y[N]; in the data block, the latest syntax should be array[N] int<lower=1, upper=K> y.

You are a true godsend! It worked. I could not find a solution to this ANYWHERE. Thanks a ton.

This is not supported since Stan version x.yy. See Array data types for the current syntax. And maybe add in …

The next release will feature an improved message in this case

I’m running into the same error, though it does not involve an mis-specified integer array (at least I do not think it does). Any help is greatly appreciated. Th error is: Compiling Stan program… Syntax error in ‘/var/folders/m7/zgrjwxmj76vcyj3w0shwp5p00000gn/T/Rtmp7upG1r/model-5bd433ab8474.stan’,…

[image] npretnar: vector[J] ln_lq[H]; vector[J] lw_lP[H]; These lines in your data block seem to be the issue - they’re also using the removed array syntax and need to be array[H] vector... instead. I get a different error message than you that points me to these lines when I try to compile y…
