Dear All,

An exponential model is fitted to empirical semivariogram using *gstat of R
package*. The variogram parameters obtained is
  model      psill   range
1   Nug 0.04281109 0.00000
2   Exp 0.76810071 5.45954
where the nugget effect is 0.04, sill is approximately 0.80, and range is
5.5.
Since exponential model approaches the sill asymptotically, its practical
range of spatial dependency is reported by literature to be distance at
which the semivariance is 95% of the sill.
Having obtained 5.5 as my range from the analysis, how do I estimate the
practical range at 95% of sill?

Thank you.
