WebMay 9, 2024 · We can convert the conditional equations to marginal moments with some simple calculations. Suppose we observe longitdinal data with three time points per person, taken at the same three time points. If we model these points as above, we have Y (i, t) = a + b*t + a (i) + b (i)*t + e (i, t) where t=1,2,3. WebUnder this model, we show that ﬁnding the persistency is tractable for zero-one optimization problems with a polynomial sized representation of the convex hull of the feasible region. Through extensive experiments, we show that the persistency computed under the limited marginal moment model is often close to the simulated
