- MixedLM.score_sqrt(params, calc_fe=True)¶
Returns the score with respect to transformed parameters.
Calculates the score vector with respect to the parameterization in which the random effects covariance matrix is represented through its Cholesky square root.
The model parameters. If array-like must contain packed parameters that are compatible with this model instance.
If True, calculate the score vector for the fixed effects parameters. If False, this vector is not calculated, and a vector of zeros is returned in its place.
