Modelling count response variables in informetric studies: Comparison among count, linear, and lognormal regression models

作者:

Highlights:

• The negative binomial often seems to be more appropriate than other count models for informetric data.

• Linear regression model predicted negative values for a few of the response variables modelled.

• Linear regression model performed worse than both the negative binomial and lognormal models.

• Overall, the negative binomial model performed slightly better than the lognormal model.
