Table 2.
The set of {Dhl} when 4 weight strata are present: all patterns of pooling coterminous strata.
| Pooling pattern index | Dummy variable pattern | Number of pooled strata |
|---|---|---|
| L = 1 (complete pooling) | Dhl= (1) for all h | H* = 1 |
| L = 2 (pool highest three weight strata) |
Dhl=(1 0) for h = 1 Dhl=(0 1) for h ≥ 2 |
H* = 2 |
| L = 3 (pool highest two weight strata) |
Dhl=(1 0 0) for h = 1 Dhl=(0 1 0) for h = 2 Dhl=(0 0 1) for h ≥ 3 |
H* = 3 |
| L = 4 (no pooling) |
Dhl=(1 0 0 0) for h = 1 Dhl=(0 1 0 0) for h = 2 Dhl=(0 0 1 0) for h = 3 Dhl=(0 0 0 1) for h = 4 |
H* = 4 |
| L = 5 (pool all but highest weight stratum) |
Dhl=(1 0) for h ≤ 3 Dhl=(0 1) for h = 4 |
H* = 2 |
| L = 6 (pool first and last two weight strata) |
Dhl=(1 0) for h ≤ 2 Dhl=(0 1) for h ≥ 3 |
H* = 2 |
| L = 7 (pool middle two strata) |
Dhl=(1 0 0) for h = 1 Dhl=(0 1 0) for h = 2, 3 Dhl=(0 0 1) for h = 4 |
H* = 3 |
| L = 8 (pool lowest two weight strata) |
Dhl=(1 0 0) for h ≤ 2 Dhl=(0 1 0) for h = 3 Dhl=(0 0 1) for h = 4 |
H* = 3 |
