scientist's level (non-integer)
The non-integer scientist's level (Todeschini and Baccini 2016) is a logarithmic approach to scaling the total number of citations and publications of an author into a single measure without the degeneracy of the integer versioned scientist's level. It is calculated as
$$\tau=\ln{\left(\sqrt{C^P}+P\right)}.$$History
