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 count (Poisson) 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.

 | 
| yvec | The vector of responses, ordered by subject, time within subject. | 
| subjectIndex | The location of the first index of subject i responses within yvec. | 
| Zmat | The design matrix for time-independent covariates ((N*T) x K0). | 
| Xmat | The design matrix for time-dependent covariates ((N*T) x Ktv). | 
| covTypeVec | The vector indicating the type of each time-dependent covariate. | 
| betaI | The current or initial estimates of the model parameters (1+K0+Ktv x 1). | 
| T | The number of time points for subject i. | 
| Tmax | The maximum number of times of observation among all subjects. |
