The problem of citation impact assessments for recent publication years in institutional evaluations
作者：
Highlights：
• Recent publication years cannot (should not) be included in a bibliometric analysis measuring citation impact.
• Using example data, the study presents various options for dealing with this problem in statistical analysis.
• One option is to show a line for citation impact regressed on ‘distant’ years showing the trend for ‘recent’ years.
• Another way of dealing with the problem is to work with the concept of samples and populations.
• The third option is the application of the counterfactual concept of causality.
