Equation for multinomial logistic regression

[Researchit]

Hello spss experts

I wonder if someone could advise how to write the equation for a multinomial logistic regression based on the spss output which can be seen here

I am an experienced spss user ( but not a statistician) and understand how to write the equation for or multiple linear regression and it's not clear to me how to do it for multinomial logistic regression I have looked up the usual online resources but none  entirely make sense

All help greatly  appreciated

The NOMREG algorithms chapter in the Algorithms doc spells out the formulas in the model.

Hi Jon - thanks for that. Sorry where us this algorithms doc?  

I am hoping for a very simple non stat example of how to write the formula for a given model, based on the info in the coefficients /  parameter estimates table


Thanks for your reply
