More precise methods for national research citation impact comparisons

作者：

Highlights：

• Two methods for comparing citation impact between different countries are introduced and tested.

• Linear regression on transformed citation data is less precise than geometric means for estimating national citation impacts.

• Geometric mean citation impact indicators are more precise than are arithmetic mean citation impact indicators.
