variograms造句

Histograms and variograms are generated for each stratigraphic layer and lithology, and preliminary simulations are run on small areas.
In applied geostatistics the empirical variograms are thus often approximated by model function ensuring validity ( Chiles & Delfiner 1999 ).
Seismic, well logs and other input data are each represented as a probability density function ( PDF ), which provides a geostatistical description based on histograms and variograms.
Each PDF describes a particular input data in geostatistical terms using histograms and variograms, which identify the odds of a given value at a specific place and the overall expected scale and texture based on geologic insight.
