Select menu: Stats | Spatial Analysis | Krige

See our video on kriging.

Computes the ordinary kriging estimates of a variable at positions on a grid from data and a model variogram. If the Model variogram menu has been used, the model and its parameters will be set to the last fitted model from that menu. If this menu is open, then using the Model variogram menu will update the the model and its parameters with the results from that menu. This uses the KRIGE directive to get the estimates and their variances.

  1. After you have imported your data, from the menu select 
    Stats | Spatial Analysis | Krige.
  2. Fill in the fields as required then click Run.

You can set additional Options before running and store the results by clicking Store.

Form of data

Lets you specify the form of the data.

Available data

This lists data structures appropriate to the current input field. The contents of this field will change as you move from one field to the next. You can double-click a name to copy it to the current input field.


Used to enter the data. If the form of the data is one-dimensional, then the data must be in a variate and if the form is two-dimensional, then the data must be in a matrix.


Model to be fitted to the variogram. he models are described in the MVARIOGRAM procedure.

Positions (1-Dimensional only)

Positions or interval.

Y Positions (2-Dimensional irregular only)

Y Positions or interval.

X Positions (2-Dimensional irregular only)

X Positions or interval.


Specifies the X and Y bounds of the region to be examined.


Dimensions (length and height) of block.

Nugget variance

A scalar specifying the nugget variance.

Gradient (Power model only)

Slope of the unbounded component.

Exponent (Power model only)

The power of the unbounded component for the power model.

Sill variance (Excluding power model)

A scalar specifying the sill variance of the spatially dependent component. For the double-spherical model this should be set to a variate containing two values or two numbers separated by a space or comma.

Range (Excluding power model)

A scalar specifying the range of the spatially dependent component. For the double-spherical model this should be set to a variate containing two values or two numbers separated by a space or comma.

Smoothness (Stable and Matern models only)

A scalar specifying the smoothness in the Matern model or the smoothness/power in the stable model. This should be a value greater than 0, and less than or equal to 2 for the stable model.

Form of variogram

Allows the variation to be defined as either Isotropic or Geometric anisotropic. An isotropic variogram has equal variances in all directions, and an geometric anisotropic variogram fits the variance as an ellipse with major and minor axes that give the directions of maximum and minimum variation, and an angle Phi (in radians) that specifies the angle of the maximum axis from the x-axis.

Anisotropic model parameters

Used to enter the parameters for when the form of the variogram is anisotropic. There are three parameters; Phi which is the angle in radians of the direction of maximum variation, the maximum gradient or range of the model and the minimum gradient or range.

Run Run the analysis.
Cancel Close the menu without further changes.
Options Opens a menu to specify additional options for the analysis and displaying output.
Defaults Reset the menu settings back to the default settings. Clicking the right mouse on this button produces a shortcut menu where you can choose to reset options using the currently stored defaults or the Genstat default settings.
Store Opens a dialog to specify names of structures to store the results from the analysis. You must supply the structure names before running the analysis.
Graphs Opens the Krige Graphs dialog to specify plots to be produced by the analysis, or if used after the analysis, produces the graphs.

Action Icons

Pin Controls whether to keep the dialog open when you click Run. When the pin is down  the dialog will remain open, otherwise when the pin is up  the dialog will close.
Restore Restore names into edit fields and default settings.
Clear Clear all fields and list boxes.
Help Open the Help topic for this dialog.
