is the mean number of cognitive errors in transition for the people who had zero errors at baseline (at the zero state) and P_0dis the probability of 5-year mortality for the people at the zero state (with zero cognitive errors at baseline). The increments β₁and β₂(for cognitive transitions and mortality, respectively) show how these values change with the baseline error state number. Note that the background parameters , ln(P_od) are significantly different between two transitions while the increments (β₁, β₂) are not.
