Kleg (X1)0.000.050.000.02
ϕo (X2)0.800.260.660.06

  • Dependent variables: |J|, dimensionless impulse magnitude; φ, impulse direction; Tc, dimensionless duration of ground contact [tc/(Lt)1/2]; and ΔEcom/Eo,com, fractional energy change. The value in each cell is the fraction of variance explained by each X variable. The last entry in each column is the R2 for the full model. Boldface indicates significance at the table-wide a = 0.05 level.
