error message

[cazlo]

I have just read some new data into MLwiN (from SPSS), which is fine, but when I specify the equation for the model, I get this error message:

"wrong parameters - possible name clash between column and macro(post)"

Unfortunately, this isn't an error message I'm familiar with.

Does anyone know what it means and how I might resolve the problem?

Many thanks.

The error message is suggesting that one of the variables in your data shares its name with one of MLwiN's included macros. If you're running a discrete response model then the macro names that it might be clashing with are:

• BVAR
• CHKORD2A
• CHKRES
• ERRCHK
• NLSETT
• NOBVAR
• NRESID
• OPTIONS
• ORDER2A
• ORDER2B
• POST
• POST_0
• PRE
• PRE_0
• PREDR1
• PREDR2
• RESID

If you have any variables that share these names then you will need to rename them before running the model.

Brilliant. Thanks, Chris, that's done it - cheers.
