In the health-plus-exposure models, there is heterogeneity in the residual variance between the communities. Standardized residual variance is the difference between the observed score and the Rasch estimated score divided by the square root of the Rasch model variance. Further, on this issue of data collection, it is important to recognise that the data were collected at the one time point and so future longitudinal work is needed to explore the stability of constructs over time and to provide greater scope to partial out residual variance that in this study was manifested in student-level variance. |
