Table S4. Citation rates.
Linear model for the citation rates after log1p transform. We repeated the analysis using Scopus citation information collected on two different dates nearly 6 months apart. We report the coefficients for both datasets:
| February 29th 2016: | |||||
|---|---|---|---|---|---|
| coef | std err | z | P>|z| | [95.0% Conf. Int.] | |
| Intercept | 0.0038 | 0.002 | 2.538 | 0.011 | 0.001 0.007 |
| Editor_As_Reviewer[T.True] | 0.0025 | 0.001 | 4.465 | 0.000 | 0.001 0.004 |
| Total_Decision_Time | -2.812e-05 | 5.27e-06 | -5.338 | 0.000 | -3.84e-05 -1.78e-05 |
| Unique_Reviewers | 0.0007 | 0.001 | 1.241 | 0.215 | -0.000 0.002 |
| July 11th 2016: | |||||
| coef | std err | z | P>|z| | [95.0% Conf. Int.] | |
| Intercept | 0.0052 | 0.002 | 2.448 | 0.014 | 0.001 0.009 |
| Editor_As_Reviewer[T.True] | 0.0024 | 0.001 | 3.059 | 0.002 | 0.001 0.004 |
| Total_Decision_Time | -3.081e-05 | 7.42e-06 | -4.155 | 0.000 | -4.54e-05 -1.63e-05 |
| Unique_Reviewers | 0.0017 | 0.001 | 2.302 | 0.021 | 0.000 0.003 |
The effect of the number of unique reviewers on citation rates increases slightly in the second dataset, while the other coefficients remain very similar.
