Estimation Features: 

• multiple grades can be estimated in a single run 
• optimization of sample searching for fast processing speed 
• the same grade can be estimated by different methods 
• different search volumes and estimation parameters can be used for the different grades 
• rectangular or ellipsoidal search volume with anisotropy 
• a dynamic search volume allowing the volume to be increased if there are insufficient samples 
• restriction of the number of samples by octant 
• restriction of the number of samples by key field 
• estimation by zone, with separate parameters for each zone 
• wide selection of variogram model types for both normal and lognormal kriging 
• automatic transformation of data if the input model is a rotated model
• calculation of recovered values for different cutoffs
• unfolding option available for all estimation types 
• parent cell estimation 
• selective update of partial model

Estimation Methods: 

• Nearest Neighbor
• Inverse Power of Distance
• Ordinary Kriging
• Simple Kriging
• Lognormal Kriging
• Indicator Kriging
• Sichel's t Estimator
