Calculate Weight in Meta-Analysis
Calculate weight in meta-analysis is a crucial step in combining the results of multiple studies. It helps to give more weight to studies with smaller sampling errors…
- Enter the number of studies.
- Input the effect size and variance for each study.
- Click ‘Calculate’.
The formula used is: w = 1 / (v + k), where w is the weight, v is the variance, and k is a small positive constant…
| Study | Effect Size | Variance | Weight |
|---|---|---|---|
| 1 | 0.5 | 0.25 | 2.0 |
- Always check the assumptions of the studies.
- Consider using random-effects models for heterogeneity.
