Despite the same data, PS matching works fine in version 26, but gives an error in version 27.

Since my product is a Korean version, some of the contents in Korean have been translated into English.

>Error # 1. Command name: /MATCHIT

> The first word of a line is not recognized as an SPSS Statistics command.

> This command execution was aborted.

MATCH=NEAREST

EST =LOGIT

RATIO = 1

CALIPER = 0

DISCARD = CONTROL

/OPTIONS DETAILEDBAL

>Error #1. Command name: /OPTIONS

> The first word of a line is not recognized as an SPSS Statistics command .

> This command execution was aborted.

/OUTPUT MATCHED.

>Error # 1. Command name: /OUTPUT

> The first word of a line is not recognized as an SPSS Statistics command .

> This command execution was aborted.

That output indicates that PLS is not installed in V27. You will need to get it from the Extension Hub or here

You may need Admin permission to install it.

Remember that it also requires the third-party libraries numpy and scipy.

Thanks, but no change. The same error persists.

If there are any blank lines in the syntax generated by the dialog box, they need to be deleted. Paste the syntax to check.

If that isn't the problem, run this code in a syntax window to get more information.

begin program python3.

import PLS

print(PLS)

end program.
