Following thewikipedia articleon multinomial logistic regression i do not fully understand why how to get from the "independent binary regressions" to the "log-linear model". At school we discussed what wikipedia calls the approach of "independent binary regressions". With the pro...

As the probabilities of each class must sum to one, we can either definen-1independent coefficients vectors, orncoefficients vectors that are linked by the equation\sum_c p(y=c) = 1. The two parametrization are equivalent. See also in WikipediaMultinomial logistic regression - As a log-linea...
(Wikipedia, 2018) ⇒ https://en.wikipedia.org/wiki/Softmax_function Retrieved:2018-2-11. In mathematics, the softmax function, or normalized exponential function, is a generalization of the logistic function that "squashes" a -dimensional vector [math]\displaystyle{ \mathbf{z} }[/math] ...
https://en.wikipedia.org/wiki/Multinomial_logistic_regression (look at "Note that not all of the \beta_k vectors of coefficients are uniquely identifiable."). You can multiply (or add a constant to) the outcome mu vector and not change the result of the softmax. I'm not sure which th...
The expression on the LHS of the first equation is the usual logit and the LHS of equation two is the generalised logit as seen in the Wikipedia article on multinomial logistic regression. My regression equations describe two logistic regressions of sorts, one nested within ...
