SPSS Statistics

I can't be sure without having your data, but I think I have fixed this.  It will get posted on the Extension Hub once the fix is confirmed, but download this file

STATS SPLINES.spe

and install it via Extensions > Install Local Extension Bundle

and try it out.

Please let me know whether it works or not.  If it does not work, I will need a data sample that shows the failure.

The new splines extension has hopefully been installed as intended, there were no error messages. But it still does not work. I have tried with both the original dataset and the simulated data for which I want to make predictions. For generating the data and the spline part I have used the following syntax:

NEW FILE.
INPUT PROGRAM.
LOOP diameter=20 TO 80 BY 2.
END CASE.
END LOOP.
END FILE.
END INPUT PROGRAM.
EXECUTE.
DATASET NAME spline_test.

STATS SPLINES VARIABLES=diameter DATASET=splines
/TRANSFORMATION TYPE=NATURALSPLINE DF=5 BOUNDS=20 80
/OPTIONS OUTNAMES=VARNAME DISPLAYKNOTS=YES.

Anything in the setup which I have misunderstood? 

This is what I get with the updated command.  What do you see?

Strange. I get the same error message as before. It runs as intended when there is no BOUNDS option, so the extension works at least partially.
I also tried to uninstall the extension through the Extension Hub followed by a new install, but the result was the same. Could it be the communication with R that causes this?

 I don't know what went wrong, but try installing this version

STATS SPLINES.spe   

(link corrected)

using Extensions > Install Local Extension Bundle

Don't go to the Extension Hub

Thanks! I switched to another computer, and the extension runs there. It's still strange that it won't work on the first machine, but it will be left as a small mystery.

Did you get that latest update?  Maybe the first machine still has the older one.
