Quantifying journals

Impact factor

https://en.wikipedia.org/wiki/Impact_factor

impact = c(year 0) / (n(year –1) + n(year –2))

e.g. 6 = 600 / 100

Pros: publishing more, low cited articles reduces the impact factor

Cons: Distribution can be highly skewed, affected by a few highly cited papers

h-index

https://en.wikipedia.org/wiki/H-index

h-index = max(n(articles with n citations))

Pros: less affected by a few highly cited papers (n represents how many of those there are)

Cons: can publish many low cited articles without reducing the score

Eigenfactor

https://en.wikipedia.org/wiki/Eigenfactor
