I think Jarno Vanhatalo did all these necessary derivatives for GPstuff…

#42

Do you have the code somewhere??

#43

I asked Jarno Vanhatalo as he should remember better where to look (and if he doesn’t remember then I’ll look into it).

#44

Jarno answered and I did remember partially, that is, GPstuff has all these derivatives except \frac{\partial}{\partial \theta_k} \left (\mathbf{L}(\mathbf{\theta})^T \mathbf{z} \right), although Jarno has something which is close. I know where the code for this is, but I might be easier if I live guide through some functions to point out specific lines.

I would like to see it. I have class until 11:30 EST but can attend the latter half of Stan meeting if you can you it then (Stan meeting starts 11:00EST).

Can someone make suggestions as to who can review these PRs? The PRs right now are primitive, and pretty basic.
