Table 8: Paired samples t-test analyses on comparing contact area determination methods Am-Euras. J. Agric. & Environ. Sci., 13 (4): 575-580, 2013 It means that actual or measured contact area (Ay) can be computed in two steps. At first step predicted contact area (A,) can be calculated based on contact area index (CAI), inflation pressure (P) and vertical load (W) using the three-variable linear regression model, i.e. equation 7. Second step is calculating actual or measured contact area (A,,) based on predicted contact area (Ap) using the linear model, i.e. equation 8.
