In a scalar model, `sigma` is variance, so it's nonsensical for it to be < 0, and it can't be 0, since we divide by it. However, Bogacz, following Friston, suggests setting a static `sigma` to 1. Sh…

Hi, thanks for the BGLR package!
I'm trying to fit an FA1 model, but sometimes I get this error:

PHPStan introduced call-site variance https://phpstan.org/blog/guide-to-call-site-generic-variance
But Psalm doesn't support the syntax so far. https://psalm.dev/r/8244015134
Would it be something…

covariance pvalue and CI of correlation don't always agree and there are legitimate reason for this discrepancy. @smhofer found this [post](http://www.statmodel.com/discussion/messages/22/7024.html?1…

Both for GCM and LES configurations of the model, we need to be able to accumulate various statistics (time aggregates) at runtime. For each of these, we should save _averages over time windows_ (e.g.…

This file goes through without issue, when I would expect it to complain about a variance mismatch:
```
module M {
type T
}
module M' refines M {
type T = X -> nat
}
