With LCGA models, there is not a single statistical indicator of good model fit.
Secondly, a LCGA model involving simultaneously TGP and FGA trajectories enabled us to examine whether older people belonging to particular trajectories of FGA were also more likely to belong to particular trajectories of TGP.
Including simultaneously FGA and TGP within a unique LCGA model allowed us to explore whether older people belonging to particular trajectories of FGA were also more likely to belong to particular trajectories of TGP.
Table 4 presents the transition probabilities of the final LCGA model.
LCGA results provided evidence for four FGA trajectories and three TGP trajectories.
As expected, the results of LCGA indicate that both strategies could complement each other in the everyday life of older people.
Risk analysis is a technique that exposes areas of uncertainty that are typically hidden in the traditional deterministic approach to LCGA, and it allows the decision-maker to weigh the probability of any particular outcome.
By including all possible inputs into the analysis and weighing the probability of occurrence of each, risk analysis elevates the debate from the validity of LCGA results to deciding best public policy.
