Hi,

I'm trying to make propension score matching with SPSS v.25 but it doesn't work... It always says:

* Propensity Score Matching.

begin program.

import spss, random, spssaux, codecs

try:

import FUZZY

except:

print "This procedure requires the FUZZY extension command which is not installed."

parts = [int(i) for i in FUZZY.__version__.split(".")]

if parts < [1,3,0]:

raise EnvironmentError("This procedure requires version 1.3.0 or later of FUZZY")

ds = spss.ActiveDataset()

if ds =="*":

ds = "D" + str(random.random())

spss.Submit("DATASET NAME " + ds)

ds = codecs.encode(ds) # must use code page rep here

matchgroup = "M" + str(random.random()) #temporary variable

tempdsname = "D" + str(random.random())

lrcmd = spssaux.u(r"""LOGISTIC REGRESSION VARIABLES Groupe

/METHOD=ENTER Age Bili Ascite

/SAVE=PRED(X).""")

try:

spss.Submit(lrcmd)

except:

raise ValueError("Logistic Regression step failed")

fuzzycmd = spssaux.u(r"""FUZZY BY=X SUPPLIERID=ID NEWDEMANDERIDVARS=XX

GROUP=Groupe EXACTPRIORITY=FALSE

MATCHGROUPVAR=%(matchgroup)s FUZZ=0.01 DS3=%(tempdsname)s

spss.Submit(fuzzycmd)

end program.

Additional error message: create startx process is failure.

FUZZY extension is installed so I don't understand...

I'm medical student and so lost in all that...

(I hope this gets past the spam blitz.)

Everything up to the error message in French is just echoing the code from the dialog box. No error message is actually being issued about FUZZY. But the error message in French near the end is reporting that the Python program being run is failing.

Do you get any output for the logistic regression that is run as the first step in the process?

Open a syntax window and run this code to see if any Python program can run.

begin program python3.

import spss

print("hello")

end program.

No I don't get any output for the logistic regression...

Python3 seems to be install on the computer but when I try your code it doesn't work...

"it doesn't work" doesn't tell me much. What exactly do you see when you run the little program I posted? And what type of computer are you using?
