Score at the MLE. For \(G(\theta, w)\) score function, returns \(\sum_i G(\hat{\theta}, W_i)\) if get_score_covariance = FALSE.
Arguments
mod
an object of class bbdml
numerical
Boolean. Defaults to FALSE. Indicator of whether to use the numeric Hessian and score (not recommended).
get_score_covariance
Boolean. Defaults to FALSE. Should we return a robust estimate of variance of score: \(\hat{B}(\hat{\theta}) = \sum_i G(\hat{\theta}; W_i) G(\hat{\theta}; W_i)^T\). This parameter is not intended for users.
