The table below is the output of polytomous (multinomial) logistic regression of clinical classification on insulin response (IR), steady-state plasma glucose (SSPG), and relative weight (RW). The clinical classification has three categories: 1 = overt diabetes, 2 = chemical diabetes, and 3= normal (which has been used as reference category).

Write the polytomous logistic regression model in terms of logit functions:
