Research evaluation with ChatGPT: Is it age, country, length, or field biased? - regression coefficients

Coefficients extracted from 26 regressions for ChatGPT scores against the variables above (except Year x 5, added for illustrative purposes). Country names are for first authors, and only the ten countries with the most articles in Scopus were included. Error bars show the minimum and maximum values from the 26 broad field estimates (not always statistically significantly different from 0). The coefficients can be compared between countries but none of the other coefficients should be compared.Graphs are reported for each independent variable.The data is from the paper, "Research evaluation with ChatGPT: Is it age, country, length, or field biased?"
