Dear List,
The following formula is given for a spherical model in variofit (geoR).
/rho(h) = 1 - 1.5 * (h/phi) + 0.5(h/phi)^3 if h < phi , 0 otherwise
/Could anyone explain what the term "if h<phi, 0 otherwise" means? Which
part of the equation becomes 0 if h>phi?
And shouldn't there be a * between 0.5 and (h/phi)?
Thanks in advance,
Anna
