COORDINATES Statement
- COORDINATES | COORD coordinate-variables ;
The following two options
specify the names of the variables in the
DATA= data set containing the values of the
x and y coordinates of the data.
Only one COORDINATES statement is allowed, and it
is applied to all PREDICT statements.
In other words, it is assumed that all
the VAR= variables in all PREDICT
statements have the same
x and y coordinates.
This is not a limitation. Since each
VAR= variable is processed separately,
observations for which the current
VAR= variable is missing are excluded.
With the next VAR= variable, the entire
data are read again, this time excluding
missing values in this next variable.
Hence, a single run of
PROC KRIGE2D can be used for variables
measured at different locations without
overlap.
- XCOORD= (variable-name)
- XC= (variable-name)
-
specifies the name of the variable containing
the x coordinate of the data locations
in the DATA= data set.
- YCOORD= (variable-name)
- YC= (variable-name)
-
specifies the name of the variable containing
the y coordinate of the data locations
in the DATA= data set.
