We next consider the difficulty of the items for the eight-dimensional model (Table 4).
According to the AIC, the results favoured the two-dimensional models (Table 5).
The predictive abilities (ρ-GP-CV) per location-year combination showed a rather different pattern for best models within locations; however, the two-dimensional models were also more frequently selected than one-dimensional models (Table 6).

The likelihood ratio (LR) test supported our assumption for H1.1 and the two-dimensional model M1 (Table 2, comparison of M1 and M2, (Δχ (1) 2 = 26.69, p < .001).001
Results show that model 4, the four-dimensional model (see Table 1), is superior: it has lowest AIC, AICc, and BIC values, and the likelihood-ratio tests show statistically significant improvements in model deviance compared to both of the 2-dimensional models.

Using an n-dimensional array of values as a model (table model).
These models range from ones that can be described as 'rational', such as the Knowledge-Driven Model, to others that are more one dimensional, such as the Political Model, to fluid, multi-dimensional, more complex models like the Interactive Model (Table 1).
The snowflake schema represents a dimensional model which is composed of a central fact table and a set of constituent dimension tables which can be further broken up into subdimension tables.
The dimensional model consists of star joins and dimension tables.
