Description
Minimal working example
@model function gdemo(x, y)
s² ~ InverseGamma(2, 3)
m ~ Normal(0, sqrt(s²))
x ~ Normal(m, sqrt(s²))
y ~ Normal(m, sqrt(s²))
end
chain = sample(
gdemo(1.5, 2.0),
MH(:m => Normal(0, 1)),
10
)Description
s² is sampled once at the start of the chain and isn't touched again. More intuitive behaviour would be to error.
