Calculation |
citation
count |
sum of citation counts for
all works by the individual identified in Publish or
Perish |
e |
e is square root of the
(sum of citations of all works contributing to h minus h2) |
h |
h is the highest number for which h works have been cited at
least h times
(also based on works identified in Publish or
Perish) |
hm |
hm is the sum of
works contributing to h fractionalized by the number of authors |
Icumulative |
average of the four
indicators above after standardizing each separately (M = 0, SD = 1) |
citesCS |
citesCS = log(citation count) – [5.461 +
(current year – PhD year + 1)*.0803]; presented in standardized units in
article (original M = 0.00074, SD = 1.17); constants are the intercept and slope
estimates from a regression of years since PhD predicting log(citation count) of this
sample of 611 scientists |
eCS |
eCS = log(e) – [2.505 + (current year – PhD year + 1)*.0383];
presented in standardized units in article (original M = -0.00025, SD = 0.65);
constants are the intercept and slope estimates from a regression of years
since PhD predicting log(h) of this sample of 611 scientists |
hCS |
hCS = log(h) – [1.929 + (current year – PhD year + 1)*.0413];
presented in standardized units in article (original M = 0.00021, SD = 0.55);
constants are the intercept and slope estimates from a regression of years
since PhD predicting log(h) of this sample of 611 scientists |
hm.CS |
hm.CS = log(hm) – [1.220 +
(current year – PhD year + 1)*.0485]; presented in standardized units in
article (original M = -0.00018, SD = 0.56); constants are the intercept and slope
estimates from a regression of years since PhD predicting log(h) of this sample of 611
scientists |
