+<p>When multinomial logistic regression is computed before the multinomial clustered variance calculation, it uses a default reference category of zero and the regression coefficients are included in the output table. The regression coefficients in the output are in the same order as multinomial logistic regression function, which is described below. For a problem with <img class="formulaInl" alt="$ K $" src="form_117.png"/> dependent variables <img class="formulaInl" alt="$ (1, ..., K) $" src="form_118.png"/> and <img class="formulaInl" alt="$ J $" src="form_119.png"/> categories <img class="formulaInl" alt="$ (0, ..., J-1) $" src="form_120.png"/>, let <img class="formulaInl" alt="$ {m_{k,j}} $" src="form_121.png"/> denote the coefficient for dependent variable <img class="formulaInl" alt="$ k $" src="form_97.png"/> and category <img class="formulaInl" alt="$ j $" src="form_122.png"/>. The output is <img class="formulaInl" alt="$ {m_{k_1, j_0}, m_{k_1, j_1} \ldots m_{k_1, j_{J-1}},
  m_{k_2, j_0}, m_{k_2, j_1} \ldots m_{k_K, j_{J-1}}} $" src="form_323.png"/>. The order is NOT CONSISTENT with the multinomial regression marginal effect calculation with function <em>marginal_mlogregr</em>. This is deliberate because the interfaces of all multinomial regressions (robust, clustered, ...) will be moved to match that used in marginal.</p>
