Reference 27 is omitted from the last sentence of the second last paragraph of the Methods section. The sentence should read: In addition, as a supplementary analysis, we made these comparisons for estimates from two models reported by Lazer et al., who developed regression models to improve upon GFT estimates [14, 27].

The reference is: Lazer D, Kennedy R, King G, Vespignani A (2014) Replication data for: The parable of Google Flu: Traps in big data analysis. Available: http://dx.doi.org/10.7910/DVN/24823 UNF:5:BJh9WzZQNEeSEpV3EWs+xg== IQSS Dataverse Network [Distributor] V1 [Version].
