Solving for the Logistic Regression Coefficients

Question

I have been searching for a source on how to compute the coefficients for logistic regression, but haven't found any. I suppose it is very easy to find like linear regression.

Can you kindly suggest a source?

Thanks

There are no "closed form" expressions that parallel those for linear regression i.e. no equivalent of $$ \hat{\beta}=(X^T X)^{-1} X^T y $$ The coefficients for logistic regression are found numerically from maximum likelihood equations. There are plenty of references available e.g. this or this
