PROC VARIOGRAM Statement
- PROC VARIOGRAM options ;
You can specify the following options in the
PROC VARIOGRAM statement.
- DATA=SAS-data-set
-
specifies a SAS data set containing the
x and y coordinate variables
and the
VAR statement variables.
- OUTDISTANCE=SAS-data-set
- OUTDIST=SAS-data-set
- OUTD=SAS-data-set
-
specifies a SAS data set in which to store summary distance
information. This data set contains a count
of all pairs of data points within a given
distance interval. The number of distance
intervals is controlled by the
NHCLASSES= option in the COMPUTE statement.
The OUTDISTANCE= data set is useful for plotting
modified histograms of the count data for determining
appropriate lag distances.
See the section "OUTDIST=SAS-data-set "
for details.
- OUTPAIR=SAS-data-set
- OUTP=SAS-data-set
-
specifies a SAS data set in which to store distance
and angle information for each pair of
points in the DATA= data set.
This option should be used with caution
when the DATA= data set is large. If
n denotes the number of observations
in the DATA= data set, the
OUTPAIR= data set contains [(n(n-1))/2]
observations unless you restrict it
with the OUTPDISTANCE= option
in the COMPUTE statement. The
OUTPDISTANCE= option in the COMPUTE
statement excludes pairs of points
when the distance between the pairs
exceeds the OUTPDISTANCE= value.
See the section "OUTPAIR=SAS-data-set"
for details.
- OUTVAR=SAS-data-set
- OUTVR=SAS-data-set
-
specifies a SAS data set in which to store the
continuity measures.
See the section "OUTVAR=SAS-data-set "
for details.
