| Level 1: | yijk = π0jk + π1jk(T1) + π2jk(T2) + π3jk(T3) |
| + π4jk (T4) + π5jk (T5) + eijk | |
| Level 2: | π0jk = β00k + r0jk |
| π1jk = β10k | |
| π2jk = β20k | |
| π3jk = β30k | |
| π4jk = β40k | |
| π5jk = β50k | |
| Level 3: | β00k = γ000 + u00k |
| β10k = γ100 + u10k | |
| β20k = γ200 + u20k | |
| β30k = γ300 + u30k | |
| β40k = γ400 + u40k | |
| β50k = γ500 + u50k |
