WebMay 6, 2016 · I am trying to find the Fisher Information Matrix for β = ( β 1, β 2). I know that the log-likelihood for one observation is: l ( β 0, β 1) ∝ − 1 2 σ 2 ( y − β 0 − β 1 x) 2 Hence, we have that the observed information matrix (before the expectation), is: ∂ 2 l ∂ β 0 2 = − 1 σ 2, ∂ 2 l ∂ β 1 2 = − x 2 σ 2, and ∂ 2 l ∂ β 0 ∂ β 1 = − x σ 2. WebThe Fisher is a nonlinear function of the weights and data. To compute its spectrum, we extend the framework developed by Pennington and Worah [13] to study random matrices with nonlinear dependencies. As we describe in Section 2.4, the Fisher also has an internal block structure that complicates the resulting combinatorial analysis.
