From: Re-expressing coefficients from regression models for inclusion in a meta-analysis
Parameter | Possible values | Rationale for the choice |
---|---|---|
nobs | 162, 8474 | Quantiles (10th, 90th) of the distribution of sample sizes for the 15 real data examples |
e | Selected from a normal distribution with mean = 0 and SD = SDea | Standard deviation selected to result in an R2 ~ 0.2, to make realistic models (Aslibekyan et al., 2014) [17] |
βDGM | -15, 0.5, 1, 10, 30 | Broad range of effect sizes encompassing those in the real data examples |
Logbase | 2, e, 10 | Log bases used in the 15 real data examples |
σ | 0.25, 0.45, 0.65, 0.85 | Selected values cover the approximate range of σ values in the 15 real data examples |
Median (µ = log(median)) | 0.25, 0.5, 1, 2, 4, 8, 16, 32 | Selected values cover the range of median exposure in the 15 real data examples |
