| method_class | Computation |
| method_description | Averaged maximum ground cover over two subplots. Ground cover computed from weekly images analysis. Maximum ground cover computed from ground cover dynamic modeled using time to event Beta Growth model. |
| formula | Ground_Cover=Maximum_Ground_Cover*(1+(Time_From_Emergence_To_Maximum_Ground_Cover-Time_From_Emergence)/(Time_From_Emergence_To_Maximum_Ground_Cover-Time_At_Inflection_Point))*(Time_From_Emergence/Time_From_Emergence_To_Maximum_Ground_Cover)^(Time_From_Emergence_To_Maximum_Ground_Cover/(Time_From_Emergence_To_Maximum_Ground_Cover-Time_At_Inflection_Point)) |
