Simulation | Model parameters | Study parameters | Values allocated through simulation |
---|---|---|---|
1 | θ = 0.5 | si fixed at 0.1, 0.2, 0.5, 0.8 and 0.9 for studies 1 to 5 respectively | N was randomly allocated between 50 and 1000 in steps of 50 with N/2 in each group (intervention/control) |
β = 0 | |||
φ2 = 0.15 | δi = 0.5 + β + ɛi | ||
φi2 ≈ (φ2 – φ2si) /si | δi ~ N (0.5, φi2) | ||
2 | Same as simulation (1) |
Qi randomly allocated
between 0.1 and 0.9. Rest same as simulation (1) |

3 | β = 0.1 | Same as simulation (1) | δi ~ N (0.6, φi2) |
