For conditional individual response profiles use a logistic random-intercept model for repeated binary outcomes. Introduce a subject effect independently across subjects and independently of treatment and baseline covariates, under the specified model. Conditional on , assume the three responses are independent Bernoulli random variables with
Here is persistent unmeasured subject heterogeneity and its variance. It induces dependence after integration: for distinct visits, the response covariance is , generally positive. This is a complete joint generalized linear mixed model, unlike a mean-only GEE specification.
Under missing at random conditional on the observed responses and baseline variables, with distinct parameters for missingness and outcomes, the missingness model is ignorable for likelihood inference. Let . The outcome observed-data likelihood is
The omitted Bernoulli factors sum to one over missing outcomes. Fit the fixed coefficients and by maximizing this integrated likelihood, with suitable quadrature or another justified integration method. If , use the limiting point-mass model. Correct response and random-effect distributions, identifiable coefficients and regularity are needed; the latent distribution assumption is not merely a convenient working covariance.
For patient , combine the fitted model with the posterior density of proportional to its normal density times that patient's observed Bernoulli factors. Integrating over this posterior gives a patient-specific predicted response profile. The treatment odds ratio for a fixed and the same baseline variables is . This conditional contrast does not by itself identify each person's unobserved causal treatment effect: a parallel-arm trial observes only one treatment per person. Random slopes or heterogeneous treatment effects require further modelling and sufficient information; they are not implied by fitting a random intercept.
