Multiple linear regression modeling the influence of competitive ability measured two months previously (2 month-CA; the pairs comprising better competitors were the baseline group), contest experience received one month previously (1 month-W/L; the pairs where both contestants received a winning experience were the baseline group) and contest experience received one day previously (1-day-W/L; the W-N pairs where the focal individuals received a winning experience were the baseline group) on the latency to gill displays, latency to attacks and escalation duration, controlling for the body size and the strain type of the contest pairs. Ndf: numerator degree of freedom; Ddf: denominator degree of freedom.
