Description Usage Arguments Examples
This function calculates the values of the derivatives of all valid moment conditions for a single subject in a longitudinal study with continuous (normal) outcomes. It allows for unbalanced data, and uses user-defined types of time-dependent covariates to determine validity of moment conditions. The function returns a matrix of derivatives for all valid moment condition for subject i.
