|Data from RAE and Web of Knowledge: treat with caution!|
- Research income and H-index are positively correlated, r = .74 (95%CI .59-.84) as we would expect. Both variables are correlated with the number of staff entered in the RAE, but the correlation between them remains healthy when this factor is partialled out, r = .61 (95%CI .40-.76).
- Institutions coded as doing neuroimaging have bigger grants: after taking into account differences in number of staff, the mean income for departments with neuroimaging was £7,428K and for those without it was £3,889K (difference significant at p = .01).
- Both research income and H-index are predictive of RAE rankings: the correlations are .68 (95% CI .50-.80) for research income and .79 (95% CI .66-.87) for H-index, and together they account for 80% of the variance in rankings. We would not expect perfect prediction, given that the RAE committee went beyond metrics to assess aspects of research quality not reflected in citations or income. And in addition, it must be noted that the citations counted here are for all researchers at a departmental address, not just those entered in the RAE.
