Method synopsis

Confirmatory path analysis using structural equation modeling to test hypothesized direct and indirect causal relationships between social factors, behavioral traits, and problem-solving success. Uses directed separation tests to evaluate model fit.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Social position indirectly influences the traits yellow-bellied marmots use to solve problems (2021), Animal Cognition. Implementations in other papers (listed below) may differ.

1. Dominance rank calculation
   Used Clutton-Brock index of social dominance to calculate relative rank. CBI calculated from ratio of wins and losses during agonistic events for each individual using equation (B + b + 1)/(L + l + 1), where B is total number of individuals 'beaten' who previously lost interaction to focal individual, b is number of individuals who those individuals who were 'beaten' have won against, L is number of individual 'winners' who have won against focal individual, and l is number of individuals to whom 'winners' have lost. Relative rank calculated and standardized with respect to total number of individuals present in group.
   Quantities: Relative rank calculated for each individual, standardized 0-1 scaleDuration: Post-field computational analysisConditions: Based on agonistic interaction outcomes throughout season
   Equipment: statistical software for calculations
