Returns the model’s Hessian matrix.
Calculates the Hessian matrix for the linear mixed effects model with respect to the parameterization in which the covariance matrix is represented directly (without square-root transformation).
|Parameters:||params (MixedLMParams or array-like) – The model parameters at which the Hessian is calculated. If array-like, must contain the packed parameters in a form that is compatible with this model instance.|
hess – The Hessian matrix, evaluated at |
|Return type:||2d ndarray|
