The KRIGE2D Procedure


The following statements are available in PROC KRIGE2D.

PROC KRIGE2D options ;
COORDINATES | COORD coordinate-variables ;
GRID grid-options ;
PREDICT | PRED | P predict-options ;
MODEL model-options ;

The PREDICT and MODEL statements are hierarchical; the PREDICT statement is followed by one or more MODEL statements. All the MODEL statements following a PREDICT statement use the variable and neighborhood specifications in that PREDICT statement.

You must specify at least one PREDICT statement and one MODEL statement. You must supply a single COORDINATES statement to identify the x and y coordinate variables in the input data set. You must also specify a single GRID statement to include the grid information.

The following table outlines the options available in PROC KRIGE2D classified by function.
