- regression analysis
-
an analysis of the nature of the relationship between two or more variables , expressed as a mathematical function. On a scatter plot, this relationship is diagrammed as a line drawn through data points. A straight line indicates simple regression; a curve indicates a higher-order regression.
- relative coordinates
-
the coordinates measured from a point other than the origin, usually the endpoint of the last graphics element drawn. See also absolute coordinates.
- relative move
-
a move that repositions the graphics element by a specified distance from its current location. See also absolute move.
- replay
-
to display graphics output that is stored in a catalog entry.
- response data set
-
a SAS data set the GMAP procedure uses that contains data values associated with map areas and one or more identification variables. See also identification variable, response values, and response variable.
- response levels
-
the individual values or ranges of values into which the GMAP or GCHART procedure divides the response variable. See also midpoint .
- response values
-
values of a response variable that the GMAP procedure represents on a map as different pattern/ color combinations, or as raised map areas (prisms), spikes, or blocks of different heights. The GCHART procedure represents response values as bars, slices, spines, or blocks. See also midpoint.
- response variable
-
the SAS data set variable in a response data set the GMAP procedure uses that contains data values associated with a map area. Response variables used by the GCHART procedure contain data values associated with bars, slices, spines, or blocks. See also chart variable, response data set, response levels, and response values.
- RGB
-
a color-coding scheme that specifies a color in terms of levels of red, green, and blue components . The levels of each component range from 0 to 255. See also CMYK, HLS, and HSV.
- rotate
-
in the graphics editor, to turn a graphics object about its axis.
- RUN group
-
in SAS procedures, a set of statements ending with a RUN statement.
