This function determines the starting values for estimation of parameters in the water retention models. The input data must contain at least the x (suction potential) and y(moisture contents) variables. It gives the starting values as close to the expected estimates as possible.
This is the water retention data with at least x (suction potential) and y(moisture contents) variables. The number of rows of the data should be at least 4 entries/levels of suction potential
The data contains x columns and y columns which are used by the function. The initial x value should not be zero but something close like 0.001
A vector of five values: pars: thr- The residual moisture content, pars: ths- The saturated moisture content, Pars: alp- Inverse of air entry potential, pars: nscal-index of pore-size distribution, and pars: mscal-scaling parameter related to nscal
