The Stan model for dogs_log is broken in that it doesn't have support on R^2. The problem is here:
parameters { vector[2] beta; } ... beta[1] ~ uniform(-100, 0); beta[2] ~ uniform(0, 100);
The right thing to do is this:
parameters { real<lower=-100, upper=0> beta1; real<lower=0, upper=100> beta2; }
It should also be vectorized for efficiency.
Now fixed in 0.4
