Model:η=β0+β1X1+β2X2+...+βkXk with probability(gregarious)=eη/(1+eη)
Significance values indicate the extent to which each variable contributes to the model. Positive coefficients indicate positive correlation with gregarious classification. X-distance varies from +1 (nearest stimulus group) to –1 (farthest from stimulus group)
R values can range from–1 to +1; positive values indicate that as the variable increases so does probability (gregarious)
