A simple matrix formula is given for the observed information matrix when the EM algorithm is applied to categorical data with missing values. The formula requires only the design matrices, a matrix ...

In Part I of this paper [SIAM J. Numer. Anal., 25 (1988), pp. 1055-1073], a Riccati transformation method for solving linear boundary value problems for ordinary differential equations is presented.

Complex matrices, diagonalisation, special types of matrix and their properties. Jordan normal form, with applications to the solutions of differential and difference equations. Singular values, and ...

This is the equivalent of linear algebra—performing matrix multiplication. However, AI models are often used to find intricate patterns in data where the output is not always proportional to the ...
