Create a scatterplot with a particular R squared (fake-data generator)?

drmmmcmillian@gmail.com
Hi everyone,
What syntax can I use to generate a scatterplot with a particular R squared, without having access to the raw data? Is there an easier way to do this than in SPSS?

There have been many threads on how to generate data with a given correlation
structure.  You can find them by searching the archives for <generate data
correlation> and similar terms.  Here is a solution based on an approach
from Marta GG in one of those old threads.

http://spssx-discussion.1045642.n5.nabble.com/Generating-Samples-of-Variables-Having-a-Specified-r-Value-td1078142.html

DEFINE TWOCORRDATA(r=!TOKENS(1) /n=!TOKENS(1)).
INPUT PROGRAM.
LOOP id = 1 to !n.
. COMPUTE r1 = NORMAL(1).
. COMPUTE r2 = NORMAL(1).
. END CASE.
END LOOP.
END FILE.
END INPUT PROGRAM.
PRESERVE.
SET ERRORS=NONE RESULTS=NONE.
FACTOR
/VARIABLES r1 r2
/CRITERIA FACTORS(2)
/EXTRACTION PC
/ROTATION NOROTATE
/SAVE REG(ALL orth) .
RESTORE.
COMPUTE y1 = orth1.
COMPUTE y2 = !r*orth1 + SQRT(1-!r**2)*orth2.
EXE.
DELETE VARIABLES id r1 r2 orth1 orth2.
!ENDDEFINE.

NEW FILE.
DATASET CLOSE ALL.

* Suppose I want r = 0.7, and r^2 = 0.49.
* MACRO call (with n=10 & r=0.7) *.
TWOCORRDATA r=0.7 n=10.

CORRELATIONS y1 with y2.

* Chart Builder.
GGRAPH
  /GRAPHDATASET NAME="graphdataset" VARIABLES=y1 y2 MISSING=LISTWISE
REPORTMISSING=NO
  /GRAPHSPEC SOURCE=INLINE
  /FITLINE TOTAL=YES.
BEGIN GPL
  SOURCE: s=userSource(id("graphdataset"))
  DATA: y1=col(source(s), name("y1"))
  DATA: y2=col(source(s), name("y2"))
  GUIDE: axis(dim(1), label("y1"))
  GUIDE: axis(dim(2), label("y2"))
  GUIDE: text.title(label("Simple Scatter with Fit Line of y2 by y1"))
  ELEMENT: point(position(y1*y2))
END GPL.


It may be that there is an extension command to generate simulated data too.
I just took a quick look via the Extension Hub, but couldn't find it.
Perhaps Jon can help.

Jon Peck
There isn't a full fledged extension command for this, but there is a custom dialog box, makedata.zip, posted to the old SPSS site


There is a readme file in the zip that explains how to install it.  Once installed, the dialog appears as File > New > Data with cases.  You can specify the probability distribution - there are many choices - and the correlation structure.  There are several other options.

Re: Create a scatterplot with a particular R squared (fake-data generator)?

Here's a streamlined version David Marso offered to the same thread. It uses single value transformation. I added Bruce's Chart Builder section.

* Encoding: UTF-8.

/* This syntax was posted by David Marso, Jan. 17, 2011. The macro will generate any number of correlations simply by adding additional BIV N=... lines with a different R, e.g., BIV N=1000 R=.3. It makes use of single value transformation.   */

DEFINE BIV (N !TOKENS(1) / R !TOKENS(1) ).
INPUT PROGRAM.
LOOP #=1 to !N.
COMPUTE X1=Normal(1).
COMPUTE X2=Normal(1).
END CASE.
END LOOP.
END FILE.
END INPUT PROGRAM.
DESC X1 X2 / SAVE.

MATRIX.
GET Z / FILE * / VARIABLES ZX1 ZX2.
CALL SVD(T(Z)*Z/(NROW(Z)-1) ,V,D,U).
SAVE (Z * T(V) *SQRT(D) *CHOL({1,!R; !R, 1})) /OUTFILE *.
END MATRIX.

CORR COL1 COL2 / STAT=DESC.
!ENDDEFINE .
BIV N=1000 R=.7 .
