On the Identifiability in the Latent Budget Model - Utrecht University ...
LBM(2) and LBM(3) of Table 3 are not identifiable, and we cannot interpret them since parameter estimates with values completely different from those in Table 3 may yield exactly the same goodness of fit statistic. The unidentifiability can be demonstrated by writing the model in matrix notation. If we collect , , in an I x J ...
