Score function

Score function

Say you observe data \( x \in \mathbb{R} \) from a distribution that depends on a parameter \( \theta \in \mathbb{R} \), \( x \sim p(x | \theta) \). The score function is simply the derivative of [what?] with respect to [what?]:

[\[ s(x, \theta) = \frac{\partial}{\partial ?} \quad ? \] ]
