Table 3. Influence across contests for leading/nonleading entries submitted by contestants who never took the lead, who took the lead in the same contest the entry was submitted in, or who took the lead in a different contest.

Results for fixed effects from linear mixed model: Influence ~ LeaderGroup + Increment + (1|Contestant/Contest). The first row indicates the intercept: nonleading entries submitted by nonleading contestants who never took the lead in any other contests. The following rows indicate the additional effect corresponding to each factor level indicated—bold indicates leading (either entry, contestant, or contestant in a different contest). The last row indicates the relationship of influence with performance, measured here as score increment.
