)
data |
Data frame. |
beta |
Vector of coefficients. |
t |
Time point at which to evaluate the (derivatives of) the moment functions. Also allowed to be a vector of time points (used in estimating the model under assumed time- independent coefficients). |
hp |
List of hyperparamerers. |
mi.mat |
A precomputed matrix of moment function evaluations at each
observation. If supplied, some computations can be skipped. Default is
|
m.avg |
A precomputed vector of the sample average of the moment
functions. If not supplied, this vector is computed. Default is
|
dm.avg |
Matrix of precomputed sample averages of the derivatives of the
moment functions. Default is |
dmi.tens |
3D tensor of precomputed evaluations of the derivatives of
the moment functions. Default is |
A matrix containing the partial derivatives of the variances of the moment functions. Each row corresponds to a moment function, each column corresponds to a covariate.
