Matrices, Eigenvectors, Eigenvalues and Inverses
Determining the equation for a matrix and confirming the inverse, eigenvalues
I have think the answer to question (a) is theta^2 [(1-p)I + pJ]. But when I am multiplying the sigma and the sigma inverse I still have “stuff” at the tail end of the identity……being added. I know I should be left with the identity if the two pieces are the inverses to each other.
