| Mar 22, 2015 at 15:55 | comment | added | Alecos Papadopoulos | @user47855 Yes, because $\phi()'$ is the derivative with respect to the argument shown, i.e with respect to $\beta$ and $\alpha$. But we are considering the derivatives with respect to $\mu$. So we need to take into account also $\partial \beta /\partial \mu = \partial \alpha /\partial \mu =-1/\sigma$. Start with the first derivative of $\ln H$ and you will arrive there. | |
