Fisher matrix matlab
WebThis MATLAB function returns a test decision for Fisher’s exact test of the null hypothesis that there are no nonrandom associations between the two categorical variables in x, … Webthe Information matrix is the negative of the expected value of the Hessian matrix (So no inverse of the Hessian.) Whereas in this source on page 7 (footnote 5) it says: The observed Fisher information is equal to $(-H)^{-1}$. (So here is the inverse.)
