Build the per-patient longitudinal design matrices

Shared helper for conditionalYT and conditionalYDT: constructs the longitudinal outcome matrix, fixed-effect parameter matrix, and random-effect variance-covariance pieces used by the conditional density quadratic form, for a single patient.

Usage

build_conditional_design(
  rep_num_i_list,
  data_num_i_list,
  lfit,
  Sigma,
  sigma.longitudinal,
  time_variable,
  n_longitudinal,
  long_sub_random
)

Value

A list with longitudinal_all_matrix, parameter_matrix, and cov_fac, the patient's factored covariance from cov_factor().
