I asked a question about how to obtain closed-form solutions for a particular set of three equations.
The question was placed on hold because it was not clear to some what I was asking. So, I edited the question to clarify.
In my question I provided a way to obtain closed-form solutions for a set of two equations and explained I could not do so for a set of three equations. I posted
R code showing how far I was able to get (and added some
R code as I made incremental advances after posting the question).
Eventually I was able to derive the closed-form solutions for the set of three equations in my question. In an answer I provided those solutions as well as the
R code I used to obtain them.
Nevertheless, my question was closed, and down-voted and my answer was down-voted. The answer was down-voted even though my derived closed-form solutions appear to be more accurate than estimated solutions provided by multinomial logistic regression. (Although, I did not provide such a comparison in my answer.)
Now someone has voted to delete the question.
This is all very confusing to me. I do not know how to make the question clearer. The question and answer appear, to me, to be entirely mathematical and perfectly suitable for a mathematics forum, and have abundant utility for further exploration of multinomial statistics (by allowing a comparison of 'truth' vs estimation).
Why is such a question and answer considered unsuitable for this forum?
I now see that my correct solution has been deleted.
