Sensitivity of the proposed moments estimators to varying degrees of variation in the covariate process, σ2, under simulation case (a) for general unsynchronized binary response. Relative mean squared deviation error is reported for both varying coefficient functions β0 (ME0) and β1 (ME1), along with deviation measures for the components of the varying coefficient function estimators, as defined in Section 5.1. Percentiles of the deviation measures presented are estimated from 200 Monte Carlo runs/data sets.
