Poisson distribution p-p-plot

[drfg2008]

how can I check poisson distribution with p-p-plot.

I can find 13 distributions as test distribution, but no poisson distribution.

Q-q plots are often preferred.  The standard Statistics q-q plot only handles continuous distributions, but there is an extension command, STATS DISTFIT, that will fit various distributions, including Poisson, and can give you both a Chi-squared test and a q-q plot against those distributions.  This command shows up as Analyze>Distribution Fit on the menus once it is installed.

You can get this command from the SPSS Community website (www.ibm.com/developerworks/spssdevcentral).  It requires the R Essentials also provided on that site.

Thanks,

I have the R Essentials but can't find the file (?) for STATS DISTFIT.

Here I got stuck:

Click on IBM SPSS Statistics.  Then click on the the Extensions Commands link.

as a reference only: Windows Vista does not allow the installation in the pre-defined paths and returns an error message. Using Vista, one should not install  SPSS on the C: \ drive to avoid that problem.

[Jon K Peck]

This is why we provide environment variables for setting a different location for extensions.
SPSS_CDIALOGS_PATH
SPSS_EXTENSIONS_PATH

These can be set to specify one or more locations for extension materials and custom dialogs.
