11. Selection of the most appropriate solution was made based on both statistical and substantive considerations. This included an examination of 'goodness of fit' statistics. Recommended guidelines are that a model which fits the data well should have lower Bayesian Information Criterion (BIC), Akaike Information Criterion (AIC) and AIC3 values, although BIC has been highlighted as the most robust and consistent statistic to consider. Classification error should be low, meaning that the likelihood that someone does not really belong to the group they have been assigned is low, the model should have good stability meaning that it can be replicated and finally the resulting groups should make substantive sense.
