Mean squared error from multinomial regression

[Chris Poole-2]

Dear SPSS users,

Can anyone clarify how to calculate Mean Squared Error and the Mean Absolute
Error from the output of a multinomial regression in which I have mapped
eczema severity scores to a quality of life index (the SF-12)?

Kind regards in anticipation,

Chris.
